Vespa Installation Issue on Ubuntu 16.04 about vespa HOT 16 CLOSED

We don't provide images for Ubuntu. I guess it wouldn't be too hard to do I guess somebody would need to contribute it as we don't use Ubuntu. Perhaps you can do it?

Otherwise I suggest running Vespa inside a Docker image.

from vespa.

Not an issue @bratseth. I have used Vespa inside a Docker image. Thanks for the Quick Response.
In below line,
"curl -s --head http://localhost:8080/ApplicationStatus"
What is this "ApplicationStatus". Is it any project which runs under vespa engine ?
Above command is not giving me 200 OK result.
So, i was little bit confused. How can i resolve this? Please let me know if you have any suggestions for the same.
How can i start vespa-engine separately ?

Thanks

Is it any project which runs under vespa engine

It's a built-in API which provides information about status of the deployed application.

If you don't get 200 OK it means the server did not come up.
Run
vespa-logfmt
to check the log.

from vespa.

Yeah, Great!.
Now i got the 200 OK respone.
And i am able to run the Vespa 👍 .

Is there any way to connect the database?
I mean, i need to connect to the database(e.g. cassandra). So, is there any configuration i need to do in any project of vespa-engine?

from vespa.

We don't provide any Cassandra integration. Either PUT the documents one by one over HTTP, or, if you need high throughput use the Java HTTP client - http://docs.vespa.ai/documentation/vespa-http-client.html

from vespa.

Thanks for the quick response @bratseth .

java -jar $VESPA_HOME/lib/jars/vespa-http-client-jar-with-dependencies.jar --file feed.json --host localhost --port 8080

While executing above commange i am getting below error:
"Nov 01, 2017 4:48:27 PM com.yahoo.vespa.http.client.core.communication.IOThread cycle
INFO: Handshake did not work out localhost:8080 ssl=false"

i have deployed that "http-api-using-searcher" project and also build vespa-engine as well.
did i missed anything?
Please provide me some suggestion for the same.

from vespa.

Are there any warnings/errors in the log when you start? Check with
logfmt -l warning,error

Does it work to write single documents using the simple HTTP API as described here?:
http://docs.vespa.ai/documentation/document-api.html

from vespa.

The exact instructions in all our sample applications is tested by our build pipeline https://travis-ci.org/vespa-engine/documentation so most likely reason is that nothing runs on localhost:8080, can you telnet to it?

from vespa.

Yes, i am able to get the response from localhost:8080. But, Error remains the same while executing that command.

from vespa.

You mean telnet response or did you try the things I mentioned above?

from vespa.

Yes, i am talking about telnet response.

If you search for 'http-api-' in https://s3.amazonaws.com/archive.travis-ci.org/jobs/295691361/log.txt?X-Amz-Expires=29&X-Amz-Date=20171101T124053Z&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJRYRXRSVGNKPKO5A/20171101/us-east-1/s3/aws4_request&X-Amz-SignedHeaders=host&X-Amz-Signature=a1d43b266d5b4230009588a6df8d2c071c8e3171be71a04760292880eb9173a2 you'll see how we test and execute the README.md for that particular sample application available here https://github.com/vespa-engine/sample-apps/tree/master/http-api-using-searcher so we know that these sample apps works.

vespa-logfmt (http://docs.vespa.ai/documentation/reference/logfmt.html) from inside the running docker container might give a hint about what's going on and if you are talking to a vespa or something else with forwarded to port 8080.

from vespa.

All the issues has been resolved and everything is UP and Running.
Thanks for the Support!

I just want to know that,
According to the sample-apps examples, It always search/feed and work using particular " *.json " file. If i want to change that it search from the database.. What should i need to do ?

How vespa search the data from external database ?
Is there any way to achieve this scenario ?

Please suggest me the way for the same.
Thank You!

from vespa.

You will need to export the data from the database, convert your DB schema to a Vespa document schema and index the data into Vespa using Vespa's json feed format.

from vespa.

Okay. So, is there any option available to convert my DB schema to a Vespa document schema ?

from vespa.

There is currently no tool that will automatically convert your DB schema to a Vespa schema no.
