Mikhail Antonov commented on HBASE-15900:
-----------------------------------------
As in the support / compatibility matrix we say that branch-1.2 supports 2.7.1,
I'd propose that branch-1.3 should just build against Hadoop 2.7.2, but that's
probably up for mail list discussion.
But what version we compile HBase against shouldn't matter in your case, right?
As long as your runtime is covered as "supported" in the compatibility matrix
you should be fine?
