Junping Du commented on YARN-3411:
----------------------------------
Thanks [~vrushalic] for updating the patch. I will review and comment based on
your updated patch in plan.
bq. Sure, I can change it to java but I think, as such there should not be any
problem running ruby code with hbase, it does not add to dependencies. In fact,
the HBase Shell, which is a command line interpreter for HBase is written in
Ruby.
I see. Thanks for sharing this prospective. However, accepting code with a new
language into hadoop community is not only mvn dependency issue but also a
maintenance headache according to issues like: setting up new code convention
for new language, etc. which could take more time to reach into a consensus.
Given there is only very limited Ruby code in current patch, shouldn't be very
painful to replace it with Java. Isn't it?

> There is work that's in progress to implement the storage based on a Phoenix
> schema (YARN-3134).
> In parallel, we would like to explore an implementation based on a native
> HBase schema for the write path. Such a schema does not exclude using
> Phoenix, especially for reads and offline queries.
> Once we have basic implementations of both options, we could evaluate them in
> terms of performance, scalability, usability, etc. and make a call.
