Keith Turner commented on ACCUMULO-1708:
----------------------------------------
I propose catching Error (OutOfMemoryException extends this) in minor
compaction and halting the process. I am thinking this may be a good patch for
1.4.5, 1.5.1, and 1.6.0. A more general fix may be to make all server threads
catch Error and halt the process, could do this for 1.6. Thoughts?
> 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).
