Subject [jira] [Created] (HBASE-12478) HBASE-10141 and MIN_VERSIONS are not compatible
Date Fri, 14 Nov 2014 21:26:34 GMT
Enis Soztutar created HBASE-12478:
-------------------------------------

             Summary: HBASE-10141 and MIN_VERSIONS are not compatible
                 Key: HBASE-12478
                 URL: https://issues.apache.org/jira/browse/HBASE-12478
             Project: HBase
          Issue Type: Bug
            Reporter: Enis Soztutar
             Fix For: 2.0.0, 0.98.9, 0.99.2


HBASE-10141 is a good optimization, eliminating the need to scan already expired files (through
TTL). However, I think if MIN_VERSIONS is set, it will not ensure that there will be at least
that many versions since it bypasses the scan layer. 

I think we can just do a simple check before the HBASE-10141 optimization to see whether MIN_VERSIONS
is set for the table, and if so just do the regular old way of doing the scan in the compaction.
