> 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.
