stack commented on HBASE-10500: ------------------------------- +1 > hbck and OOM when BucketCache is enabled > ---------------------------------------- > > Key: HBASE-10500 > URL: https://issues.apache.org/jira/browse/HBASE-10500 > Project: HBase > Issue Type: Bug > Components: hbck > Affects Versions: 0.98.0, 0.96.0, 0.99.0 > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Attachments: HBASE-10500.00.patch > > > Running {{hbck --repair}} when BucketCache is enabled in offheap mode can > cause OOM. This is apparently because {{bin/hbase}} does not include > $HBASE_REGIONSERVER_OPTS for hbck. It instantiates an HRegion instance as > part of HDFSIntegrityFixer.handleHoleInRegionChain. That HRegion initializes > its CacheConfig, which doesn't have the necessary Direct Memory. > Possible solutions include: > - disable blockcache in the config used by hbck when running its repairs > - include HBASE_REGIONSERVER_OPTS in the HBaseFSCK startup arguments > I'm leaning toward the former because it's possible that hbck is run on a > host with different hardware profile as the RS. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
