Subject [jira] Commented: (HBASE-485) Two runs of PerformanceEvaluation from HBase trunk failed with region off-line error
Date Sun, 02 Mar 2008 11:44:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12574210#action_12574210
] 

Jim Kellerman commented on HBASE-485:
-------------------------------------

No, I can't figure out why it should have started failing. I did
update to latest trunk but the only issues that are even remotely
related are HBASE-473, and 428, neither of which should impact the
performance evaluation test (I wouldn't think). It must be one of
the very latest commits, because PE was working on Friday (though
I hadn't updated then) and now it reliably gets the region off-line
error.
