[jira] [Commented] (HBASE-8335) Investigate unit test performance regressions between hadoop1 and hadoop2

    [ https://issues.apache.org/jira/browse/HBASE-8335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13728010#comment-13728010 ] 

stack commented on HBASE-8335:
------------------------------

Of note, HBASE-8957 turned off SSR for unit tests.  Perhaps that made a difference?

> HBASE-7606 and HBASE-7605 showed 2-3x performance regressions when comparing running on top of hadoop1 (1.1.2) and hadoop2 (2.0.2-alpha). 
> We need to figure out why.
