Subject [jira] [Created] (ACCUMULO-1821) master recovers new WAL on recovering tablets
Date Mon, 28 Oct 2013 19:46:32 GMT
Eric Newton created ACCUMULO-1821:
-------------------------------------

             Summary: master recovers new WAL on recovering tablets
                 Key: ACCUMULO-1821
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1821
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.5.0, 1.4.4, 1.4.3, 1.4.2, 1.4.1, 1.4.0
            Reporter: Eric Newton
             Fix For: 1.4.5, 1.5.1


During root tablet assignment, unflushed mutations are recovered from the WAL, and then compacted
out.  This records a new WAL entry for the root tablet, and recovery is immediately started.
 This interferes with writing out the minorCompaction started and minorCompactionComplete
flags.  We don't want to write out anything to the WALog until the tablet has been brought
online.
