Subject [jira] [Commented] (HBASE-13339) Update default Hadoop version to 2.6.0
Date Tue, 21 Apr 2015 22:04:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14505881#comment-14505881

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

We might be hitting HDFS-7005 too. We are planning to upgrade to a Hadoop that has a patch
for HDFS-7005 applied, though it is not 2.6. 

Anecdotally I hear 2.6 is an unstable release, and that some things are not expected to be
stable until some 2.7.x, such as the rolling upgrade feature. All hearsay. Would welcome clarification
from a Hadooper with better understanding of the issues.  But given this, if we could ask,
and receive, a 2.5.3 release with HDFS-7005 then I don't think we need to move up to 2.6.

> 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.
