Mike Drob commented on ACCUMULO-1534:
-------------------------------------
Another option is to modify the hadoop io.file.buffer.size to something smaller
than the current value. In the cdh3 line it looks like it is 64k? Not sure
about other distributions.

> Key: ACCUMULO-1534
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1534
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.4.3
> Reporter: Mike Drob
> Fix For: 1.4.4, 1.5.1, 1.6.0

> I believe this issue is similar to ACCUMULO-665. We've run into a situation
> where a complex iterator tree creates a large number of decompressors from
> the underlying CodecPool for serving scans. Each decompressor holds on to a
> large buffer and the total volume ends up killing the tserver.
> We have verified that turning off compression makes this problem go away.
