Also - if you want to avoid the headache of building and configuring parquet-tools you can simply add this to your .bashrc
(or paste in console) and use docker to take care of everything.
parquet-tools() { docker run -w /home -v ${PWD}:/home nathanhowell/parquet-tools $@; }
You have to be in the same directory as the parquet file you want to inspect (since current directory will be mounted to the docker as /home
). You can then use the tools directly on any parquet file, i.e.:
parquet-tools dump fruits.parquet
from parquetjs.
I'm getting Error:TypeError: Cannot read property 'num_values' of null when trying to read 'fruits.parquet' using the read functionality of the module
from parquetjs.
I can read it fine when using @drauschenbach tool above
from parquetjs.
I get the num_values error when writing fields with null values. Not writing those fields when their value is null avoided the issue.
from parquetjs.
You might want to check out this PR here #56 which has some fixes to RLE encoding and does verification of the generated files with parquet-mr.
I think you should be able to install this branch simply by:
npm install zjonsson/parquetjs#0c7948d4fa64acf76e481256422c6f4a6ba56815
from parquetjs.
