Subject [jira] [Created] (ACCUMULO-4428) GC does not delete WAL files belonging to dead tservers
Date Mon, 29 Aug 2016 15:00:23 GMT
Adam J Shook created ACCUMULO-4428:
--------------------------------------

             Summary: GC does not delete WAL files belonging to dead tservers
                 Key: ACCUMULO-4428
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4428
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.7.2
            Reporter: Adam J Shook


The GarbageCollectWriteAheadLogs uses a Map<HostAndPort,Long> to track when it had first
seen a dead tserver, waiting an hour before deleting the files.  However, a new instance of
this class is re-created during each run of the SimpleGarbageCollector, causing the state
of the dead tservers to be lost.  All of the WAL files belonging to a dead tserver will never
be removed.
