             Summary: Error during minor compaction left tserver in bad state
                 Key: ACCUMULO-1708
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1708
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: Keith Turner
            Priority: Critical
             Fix For: 1.6.0


A tserver experienced a OOME during minor compaction.  This OOME was thrown because java could
not create a native thread.  Minor compactions only catch declared exceptions and RuntimeExceptions.
 This left the system in a state where the compaction was not running but the tserver thought
it was.  This cause"flush -w" to hang and prevented the tserver from reclaiming memory.

For whatever reason the OOME handler that kills the process did not kick in (seems it only
kicks in w/ OOME related to heap allocation).
