Hi,

Anyone using HBase 0.92 with 0.23.1 in your clusters.
We are planning to use this combination in our clusters to take the
advantage of new hadoop features and improvements.
Please give opinion on this (any known issues, suggestions).

--
Regards,
Laxman

Hi Laxman,

We've been testing this combination (more or less) as part of our CDH4
beta testing efforts. So far, pretty good results, but keep in mind
both releases are classified as alpha/beta at this point. So I
wouldn't recommend it for a production use case unless you have a long
burn-in cycle to gain confidence first.

Thanks for your quick inputs Todd.
We also will be contributing & testing this combination (HBase 0.92 + Hadoop
0.23.x)
I will be happy to share any load and contribute to make this ready for
production.

Laxman,

If you have any test scripts you can share with us, we'd appreciate it,
especially in some of the new areas that 0.92 + 0.23 covers.

In fact, if you have such tests/scripts, please do think about donating
them to project Bigtop where we can execute them regularly as part
of our testing routines.

Thanks,
Roman.

We're evaluating new features from hadoop 0.23+, including yarn,
federation, NN HA (in 0.24, will be ported to 0.23 later), with hbase 0.92.

Each of the new features brings quite some new (and deprecated)
configurations. And with security enabled, the combination can be pretty
complicated. Be prepared to dig into source code see how a configure is
used, since some important configurations can be missed from document.

Please file JIRAs against the docs when you find stuff like this! Happy to fix.

We filed some for yarn, and patches are available. There will be a
little more when we proceed.
