Subject [jira] Updated: (HBASE-694) HStore.rowAtOrBeforeFromMapFile() fails to locate the row if # of mapfiles >= 2
Date Wed, 18 Jun 2008 14:46:45 GMT

     [ https://issues.apache.org/jira/browse/HBASE-694?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bryan Duxbury updated HBASE-694:
--------------------------------

    Attachment: 694-v2.patch

Here's the patch with a little refactoring in it.

In general, I like the patch. I think it's fixing an issue we have. However, when I run the
full test suite, I get a few weird errors. TestRegionRebalancing and TestMetaUtils both fail.
Are other people seeing this problem when running the test suite?
