Subject [jira] [Resolved] (HBASE-8335) Investigate unit test performance regressions between hadoop1 and hadoop2
Date Fri, 02 Aug 2013 17:23:51 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8335?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack resolved HBASE-8335.
--------------------------

    Resolution: Invalid

Resolving as invalid.

hbase trunk on hadoop2 takes 1.30 on hadoop1 it taks 2:00.  Both run 1600 tests.

https://builds.apache.org/view/H-L/view/HBase/job/HBase-TRUNK/4330/consoleText
https://builds.apache.org/view/H-L/view/HBase/job/HBase-TRUNK-on-Hadoop-2.0.0/648/consoleText

Looking over more history, the variability is high.  Tests run on different machines and at
different times of the day.

Resovling as invalid for now.  Lets reopen if we get more to hang on.

> 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.
