[ https://issues.apache.org/jira/browse/HBASE-3862?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Heitmann updated HBASE-3862: --------------------------------- Status: Patch Available (was: Open) This patch includes both a fix for the bug and unit tests. The fix is good, but the unit tests are a little dodgy. I had to jump through some hacky hoops to trigger the race, and being a race it doesn't happen all the time. The tests may be a maintenance problem in the future, and therefore you may not want to commit them. > Tace conditions in aggregate calculation > ---------------------------------------- > > Key: HBASE-3862 > URL: https://issues.apache.org/jira/browse/HBASE-3862 > Project: HBase > Issue Type: Bug > Components: coprocessors > Affects Versions: 0.92.0 > Reporter: John Heitmann > > The AggregationClient requests aggregations from multiple region servers in > parallel. The calculations in the reducer callbacks of the AggregationClient > are not thread safe, and therefore could return an incorrect result due to > simultaneous/interleaved execution. -- This message is automatically generated by JIRA.
