Nick Dimiduk updated HBASE-10660: --------------------------------- Attachment: HBASE-10660.00.patch Simple patch. > MR over snapshots can OOM when alternative blockcache is enabled > ---------------------------------------------------------------- > > Key: HBASE-10660 > URL: https://issues.apache.org/jira/browse/HBASE-10660 > Project: HBase > Issue Type: Bug > Components: mapreduce > Affects Versions: 0.98.0, 0.99.0 > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Attachments: HBASE-10660.00.patch > > > Running {{IntegrationTestTableSnapshotInputFormat}} with the {{BucketCache}} > enabled results in OOM. The map task is running a sequential scan over the > region region it opened, so probably it's not benefiting much from a > blockcache. Just disable blockcache entirely for these scans because it's > likely the cache config detected is designed for a RS running on a different > class of hardware than that running the map task. -- This message was sent by Atlassian JIRA (v6.2#6252)
