ramkrishna.s.vasudevan commented on HBASE-14636: ------------------------------------------------ With the above approache I was able to avoid OOME with even a 2GB heap space while doing a compaction. Without this change a 2GB compaction was OOMEing without any other operations being performed. So I suggest we do the clear after every next() in compaction flow. > Clear HFileScannerImpl#prevBlocks in btw Compaction flow > -------------------------------------------------------- > > Key: HBASE-14636 > URL: https://issues.apache.org/jira/browse/HBASE-14636 > Project: HBase > Issue Type: Sub-task > Components: regionserver, Scanners > Reporter: Anoop Sam John > Assignee: Anoop Sam John > Priority: Blocker > Fix For: 2.0.0 > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
