Subject [jira] Commented: (HBASE-483) Merge tool won't merge two overlapping regions
Date Thu, 20 Mar 2008 03:34:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-483?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12580650#action_12580650

Bryan Duxbury commented on HBASE-483:

I just ran the unit tests, and all tests passed except TTMR. That makes me nervous because
Jim had a similar experience. Two occurrences is a pattern.

> hbase-480 adds a merge tool. Seems to work for two adjacent regions in tests but not
for the case where we've made two overlapping regions: i.e. both have a start key of 'A' but
one regions endkey is less than the end key of the others (See up on Lars cluster hbase-471).
 I ran the merge and it made a new region with the right start and end keys but there was
nothing in it.
> We need this tool to do fix up when hbase goes awry.
