Subject [jira] [Commented] (ACCUMULO-3397) CANDIDATE_MEMORY_PERCENTAGE is too low
Date Tue, 09 Dec 2014 22:43:12 GMT

Eric Newton commented on ACCUMULO-3397:
---------------------------------------

Yes.  The solution was to (temporarily) give the GC 80G. The first successful collection took
>24 hours.

> CANDIDATE_MEMORY_PERCENTAGE is too low

>          Issue Type: Bug
>          Components: gc
>    Affects Versions: 1.6.0, 1.6.1
>         Environment: large cluster

> On a large production cluster, file gc was delayed for several days.  The result was
millions of files that needed to be deleted.  The incremental low-memory approach failed repeatedly
with OOM errors. Recommend that CANDIDATE_MEMORY_PERCENTAGE be lowered.
