Thanks for the reviews. > Some tools OOM when BucketCache is enabled > ------------------------------------------ > > Key: HBASE-10500 > URL: https://issues.apache.org/jira/browse/HBASE-10500 > Project: HBase > Issue Type: Bug > Components: HFile > Affects Versions: 0.98.0, 0.96.0, 0.99.0 > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Fix For: 0.96.2, 0.98.1, 0.99.0 > > Attachments: HBASE-10500.00.patch, HBASE-10500.01.patch > > > Running {{hbck --repair}} or {{LoadIncrementalHFiles}} when BucketCache is > enabled in offheap mode can cause OOM. This is apparently because > {{bin/hbase}} does not include $HBASE_REGIONSERVER_OPTS for these tools. This > results in HRegion or HFileReaders initialized with a CacheConfig that > 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)
