Hbase MOB and HDP2.4

Hi,

I read this recent doc on Hbase MOB which is available as of HDP2.5. It occurred to me that purely judging on the Hbase version on Ambari > Stack Versions there is no difference in the HBase versions shipped with HDP2.4 and 2.5, both say 1.1.2

HDP2.4:
hbase(main):001:0> version
1.1.2.2.4.0.0-169, r61dfb2b344f424a11f93b3f086eab815c1eb0b6a, Wed Feb 10 07:08:51 UTC 2016
HDP2.5:
hbase(main):001:0> version
1.1.2.2.5.0.0-1245, r53538b8ab6749cbb6fdc0fe448b89aa82495fb3f, Fri Aug 26 01:32:27 UTC 2016  

Today I tested that the MOB features are really not shipped with the HDP2.4 Hbase which is unfortunate since a site wants to use MOB support on a HDP2.4 cluster.

So here is the question: Is there much between the HBase versions of HDP2.4 / 2.5? Could the 2.5 HBase jars be transplanted to HDP 2.4 just to use the new MOB features? Or is this 'definitely not recommended' 🙂

I would say it is not recommended (I am the person who ported MOB to HDP)

There hasn't been any testing on using 2.5 jars on top of 2.4

Is there particular reason why the customer cannot upgrade to 2.5 ?

Thanks

@Ted Yu

Thanks, ah yeah, you know, there is always a reason not to upgrade it seems. Maybe this is another reason to contemplate the upgrade.

bq. HBase versions shipped with HDP2.4 and 2.5, both say 1.1.2

Both 2.4 and 2.5 were based on hbase 1.1.2 but 2.5 had a lot more fixes / backports (MOB being one of them)
