Subject [jira] Commented: (HBASE-1500) KeyValue$KeyComparator array overrun
Date Fri, 12 Jun 2009 07:12:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718746#action_12718746
] 

Lars George commented on HBASE-1500:
------------------------------------

Just asking Andrew, since you lost me here a bit, the initial issue with the comparator and
the first log dump, what has that do with the later client based issues? When I check you
first set of logs there were hardly any issues (in terms of exceptions) in it. How does this
all fit together? Sorry for being thick.
