Subject [jira] [Commented] (HBASE-13339) Update default Hadoop version to 2.6.0
Date Thu, 30 Apr 2015 06:54:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14520999#comment-14520999

Andrew Purtell commented on HBASE-13339:
----------------------------------------

I missed all the fun while out sick. Appreciate the clarifications from [~cnauroth] . I think
as long as a Hadoop version bump can be handed in production as a rolling upgrade, then operationally
its no worse then our story, so doesn't constitute a major change in that respect. Rolling
downgrade not being there yet is kind of scary though. 

Should we also ensure that users can still build HBase using the earliest Hadoop version specified
as dependency on the HBase release line? eg a user can build any 1.x with -Dhadoop-two.version
set to what shipped with 1.0?

> 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.
