I created Presto client library for Ruby and Python.
They're native client library that use HTTP connection to send requests to Presto.
Ruby: https://github.com/treasure-data/presto-client-ruby
Python: https://gist.github.com/frsyuki/8296022
Do you think version management (& release cycle) should be done at this repository (facebook/presto.git)?
In other words, do you think should the code in this facebook/presto.git repository?
There is an advantage to have only one repository to manage both server (Presto) and client libraries (presto-client-{ruby,python}). It becomes easy to synchronize changes to a client library when REST API is changed.
However, in my opinion, it's too much to include Ruby or Python libraries. Because client libraries often need to solve language-specific problems such as type conversion. Or creators can relatively easily add innovation in the design of the client library if the repository & ownership is separated to another community.
It's ok to include Java client library in this facebook/presto.git because it can share a lot of code with the server implementation.
I packaged ruby client library as a RubyGem.
Implementation is still beta quality. Little document. I can work on improving the code but I welcome if someone wants to improve the code.
I'm not a pythonista. I don't know how to package library for python. I don't have intention to improve the quality any more. I'd like someone to take over the project.
The bucketing code assumes that tables declared as being bucketed actually have the correct file layout in HDFS. HiveSplitIterable
currently walks the directly structure as normal when bucketing is enabled and skips any files that don't match the bucket file. It should do this instead:
The bucket file is determined by sorting the filenames lexicographically and returning the Nth file.
presto:default> select p.foo, i.bar from pokes p, invites i;
Query 20131115_215838_00012_89y4z failed: Cross joins not yet supported
Any plan to support this important SQL feature?
Thanks

I want to know whether it is caused by incompatible versions of protobuf.
Thanks.
JDBC Connection URL format to provide Schema & Catalog name through URL. As per my understanding currently if Catalog name & Schema name is not present in the sql 'default' schema & catalog name is used.
When processing hive splits, Presto will sometimes choose to schedule the processing on a node that is not collocated with the data. There should be a flag to disable this behavior.
I have an HDFS/Hive instance set up using MySQL as a metastore.
Running the following version of Hadoop: hadoop-1.2.1
Running the following version of Hive: hive-0.12.0
Running the following version of Presto Server: presto-server-0.54
Running the following version of Discovery Server: discovery-server-1.16
Using the following Presto CLI: presto-cli-0.54-executable.jar
I have a Hive Table created as follows:
[localhost:10001] hive> describe stats;
A int None
B smallint None
C tinyint None
D tinyint None
E varchar(64) None
F smallint None
G int None
H bigint None
I int None
J bigint None
K int None
L bigint None
hour int None
# Partition Information
# col_name data_type comment
hour int None
The table appears to work well in Hive. It is correctly populated with data. However, when I attempt to query the table via Presto, I see errors:
presto:default> describe stats;

There is not a lot of debug information:

Does Presto not support 'varchar' field types?
Here're my thought about supporting UDF on Presto and I want to implement and send a pull request if the following approach is acceptable.
The core logic for the Presto functions is at FunctionRegistry.java which defineds window, aggregate and scalar types of functions.
We might want to add functions without changing Presto code, then we can implement & use experimental functions easily. But Presto doesn't have a room for UDF, UDAF and UDTF yet.
So here're an idea of how Presto could support UDF and UDAF in a othogonal way. We might not consider UDTF at this time to make thinghs simple but it would not be much different. Also supporting existing Hive UDF is out of scope of this topic and should be an issue of the HiveConnector.

At first, we can create usual unit tests by refering the function call tests at TestExpressionCompiler.java, even if it would still not be easy to create unit tests for window and aggregate functions.
In the future, we could invent a descriptive testing framework or development kit like the Hive PDT (Plugin Developer Kit): https://cwiki.apache.org/confluence/display/Hive/PluginDeveloperKit
I created a table with data of array type
create table x (

) row format delimited fields terminated by ',' ESCAPED BY '' COLLECTION ITEMS
TERMINATED BY '\002' stored as textfile;
Loaded data into it and use hive to query, all work fine with queries such as
select reasons[0] from x;
Using JDBC to query the array-typed data by "SELECT reasons FROM hive.default.x", it works fine:
["No_Week","Geo","Lg Mismatch"]
But it fails when using JDBC to query any array element such as "reasons[0]"
stmt.executeQuery("SELECT reasons[0] FROM hive.default.x");

Presto currently combines the ability to fetch query progress info with the fetching of the results. Presto should add another HTTP end point that allows fetching of query progress info, but without returning data and without counting as a heartbeat.

I tried to add the hadoop config files to the classpath but made no difference from the look at the stack trace its trying to create a NonHAProxy to connect. This is on a CDH4.3 cluster with the Cloudera recommended way of setting up HA Namenodes.
http://prestodb.io/docs/current/functions/window.html
LAG and LEAD function are missing
Syntax should be this :
LAG (value_expression [,offset] [,default]) OVER ([partition_clause] order_by_clause)
LEAD (value_expression [,offset] [,default]) OVER ([partition_clause] order_by_clause)
More info here

I have an HDFS/Hive instance set up using MySQL as a metastore.
Running the following version of Hadoop: hadoop-2.2.0
Running the following version of Hive: hive-0.12.0
Running the following version of Presto Server: presto-server-0.54
Running the following version of Discovery Server: discovery-server-1.16
Using the following Presto CLI: presto-cli-0.54-executable.jar
I have a Presto coordinator setup on a system:
[root@viper etc]# cat config.properties
coordinator=true
datasources=jmx
http-server.http.port=8081
presto-metastore.db.type=h2
presto-metastore.db.filename=/hadoop/presto/db
task.max-memory=1GB
discovery-server.enabled=true
discovery.uri=http://viper:8081
[root@viper etc]# cat node.properties
node.id=c2a9dd40-43f6-4088-9cea-ebd6b9ee923c
node.environment=production
node.data-dir=/hadoop/presto/data
[root@viper etc]# ping -c 1 viper
PING viper (172.16.100.19) 56(84) bytes of data.
64 bytes from viper (172.16.100.19): icmp_seq=1 ttl=64 time=0.057 ms

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.057/0.057/0.057/0.000 ms
The server starts fine, and (if there is a datanode configured) runs well.
I try to start the Presto server on my worker, with the following configuration:
[root@defiance etc]# cat config.properties
coordinator=false
datasources=jmx,hive
http-server.http.port=8081
presto-metastore.db.type=h2

I notice the following in the log output:
2013-12-10T15:45:57.509+0000 INFO main org.eclipse.jetty.server.AbstractConnector Started [email protected]:8081
I get a bunch of errors (see stack trace below). It appears that the Presto server is attempting to connect and failing. Any idea why?

The documentation mentions Hbase support and I thought I saw some code in the repo at some point (but not anymore).
Could someone please point me to the Hbase code? Thank you.
We need a non-hacky way to support Hadoop compression codecs that can't be shipped with Presto (for example, LZO which is GPL). Having a very basic plugin interface (inside the Hive plugin, yay) using ServiceLoader
that can add the codec to the Hadoop configuration will probably work. The plugins can bundle the native libraries like the Hadoop code already does.
Additionally, it would be good to allow compressed files to be splittable, so we would need to change split creation to use the methods from the InputFormat
.
See https://groups.google.com/forum/#!topic/presto-users/_Fe9YrZ3gYg
The Snappy codec should work but the native library is not loaded. We need to load it in HadoopNative
and make sure it is in the list of configured codecs.
When attempting to use Snappy compressed data, we get the following exception:

Hi friends:
Now I can't open the page https://groups.google.com/forum/#!forum/presto-users ,so show my question here.
I have started hiveserver and started presto-server on a machine with commands below:
hive --service hiveserver -p 9083
./launcher run
When I use the presto-client-cli command ./presto --server localhost:9083 --catalog hive --schema default ,the console shows presto:default>,input the command as show tables the console prints Error running command: java.nio.channels.ClosedChannelException,
and the hiveserver console print as below:
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

please help me ,thanks.
Hello.
I have an HDFS/Hive instance set up using MySQL as a metastore.
Running the following version of Hadoop: hadoop-2.2.0
Running the following version of Hive: hive-0.12.0
Running the following version of Presto Server: presto-server-0.54
Running the following version of Discovery Server: discovery-server-1.16
Using the following Presto CLI: presto-cli-0.54-executable.jar
The Hive instance works well when browsing directly or via Thrift:
[localhost:10001] hive> show tables;
test
[localhost:10001] hive> describe test;
foo int None
bar string None
[localhost:10001] hive> select * from test limit 1;
1 First String
I added a Presto server. I am able to connect and browse the metastore:
presto:default> show tables;
test
(1 row)
Query 20131204_201247_00006_mdebb, FINISHED, 1 node

presto:default> describe test;

However, when I attempt to select data from the table I get the following error:
Client Output:

My guess is that Presto is using a jar from an older version of Hadoop. Is there a way to correct this? I know HBASE requests that you replace their common hadoop jar with the jar in use by the HDFS instance.

Hi,
Drop table in Hive is not refleting in Presto CLI. When I create one table in Hive it is reflected in Presto CLI within few sec. but when I drop a table in Hive it was not refleted in Presto after several min. Then I "quit" from that instance and reconnect it. Then it is reflected there that the table is dropped in Hive.
Hi Presto Team:
I would like to use Presto for SQL Querying on a table that has been exist in my hbase.So far,I find Presto that has supported to query data from datasources as Hive/HDFS with SQL,but i am not sure whether it has supported to query data from a exist table of hbase as well as SQL Querying. Please give me some helps,Thank you very much.I will wait your replies online.

There's currently no way to extract values for fields in json structures whose names contain any of the special json path characters ($
, [
, ]
, .
, etc.).
The syntax for json path expressions (for json_extract
and friends) should be extended. One possible option is to allow bracket notation for field references (see http://goessner.net/articles/JsonPath/).
For example, to wanted to get the value for key "1.0" from the following structure:
{ "1.0": "apple", "2.0": "banana" }
The corresponding json path expression would be $["1.0"]
. Note that the expression uses "
instead of '
to make it fit more naturally within SQL strings.
The full schema properties should be added to the JobConf
in Hive RecordSet
before calling inputFormat.getRecordReader
so the input format can access all partition metadata
Since presto only run on jdk1.7 and it's does not have any env conf file, I wanted to set JAVA_HOME explicitly in configuration file so that it can use jdk1.7 and should not affect other jdk apps.
Is there any workaround for that?
Thanks
Deserialization is not local-dependent and thus fails if the float contains a "," instead of a ".".
Several com.facebook.presto.operator.Test*Stats are failing due to this reason.
Hi,facebook team:
When I executed sql querying with presto-cli ,the console shown below:

Please help me.
Thank you.

I have some of the previously created Hive External Tables which are created with
ROW FORMAT SERDE 'com.bizo.hive.serde.csv.CSVSerde'
.
Now while I was using Hive to query on those tables I placed the CSVSerde library inside Hive lib and as Hive uses Map Reduce Job to query tables I also had to put jar inside Hadoop.
Currently I want to query those table with Presto. But it giving me a :
MetaException(message:org.apache.hadoop.hive.serde2.SerDeException SerDe com.bizo.hive.serde.csv.CSVSerde does not exist)
exception.
I already tried by putting the CSVSerde.jar & HiveSerDe.jar inside the presto server lib. But still getting the same error. Thank you in advance.
I added a fix to this minor issue (+ one more unit test) here:

Please help me out. Thank you in advance.
Example query:
select * from hive.INFORMATION_SCHEMA.TABLES where table_name = 'task';
This fails with with "schemaName is absent!" due to MetadataUtil.checkTableName()
. Besides being the wrong exception type (should be IAE
not ISE
) that check is very confusing. It would be much simpler like this:
if (tableName.isPresent() && !schemaName.isPresent()) {
throw new IllegalArgumentException("tableName specified but schemaName is missing");
}
But the root problem is that InformationSchemaDataStreamProvider.extractQualifiedTablePrefix()
should be checking if the schema exists.
