HBase tables snippet

["vincent.peres@gmail.com" <vi...@gmail.com>]

Hi,

We have an HBase cluster containing TBs of data. As a front-end developer, I
need a snippet of some tables to run tests on local. I would like to build a
script that would export a given number of rows for a given list of tables.
I had a look at the export / import table but it export the whole table.
Could you suggest me any tool / options that might help me doing this?

Thanks a lot!
Vincent

Hi Vincent,

If you are able to provide some criteria for selecting the
rows(rowkey/composite rowkey/column) etc, you can try using Crux at
https://github.com/sonalgoyal/crux. With Crux, you can  select specific data
in HBase columns by defining filters and view the data in a tabular/chart
format.

Let me know if you need any help.

Best Regards,
Sonal

If you just need a sample of rows from tables, use the client API (e.g.,
HTable) and scan off a few hundred rows or whatever you need.  The harder
part of local unit testing is getting a coherent set of rows that makes
sense between all the tables - but that's something that every developer
has to figure out for themselves and their application.
