Subject [jira] [Created] (HBASE-7959) HBCK skips regions that have been recently modified, which then leads to it to report holes in region chain
Date Thu, 28 Feb 2013 03:55:16 GMT
Enis Soztutar created HBASE-7959:
------------------------------------

             Summary: HBCK skips regions that have been recently modified, which then leads
to it to report holes in region chain
                 Key: HBASE-7959
                 URL: https://issues.apache.org/jira/browse/HBASE-7959
             Project: HBase
          Issue Type: Bug
          Components: hbck
            Reporter: Enis Soztutar
             Fix For: 0.95.0, 0.98.0, 0.94.7


While lots of region splits going on, HBCK incorrectly reports inconsistencies since it skips
recently modified, but does not take those into account for computing the region chain.
