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.

> 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.
