Lars Hofhansl commented on HBASE-13339:
---------------------------------------

bq. Not sure why you say Hadoop 2.5.x to 2.6.x is a "major" upgrade of Hadoop.

If there's no Hadoop upgrade to run from 2.5 to 2.6 and we do not have any other compatbility
issues, we have nothing to discuss. Let's do it.

We _did_ have to run the HDFS upgrade from 2.3 to 2.6 if I recall correctly. [~apurtell].

> Current default Hadoop version is getting a little long in the tooth. We should update
to the latest version. The latest version is backwards compatible with 2.5.1's dfs and mr
so this should be painless.
