Ted Yu commented on HBASE-10017: -------------------------------- bq. -1 core tests. The patch failed these unit tests: I was more interested in finding out which test(s) possibly hung. You can attach your patch again to trigger another QA run. > HRegionPartitioner, rows directed to last partition are wrongly mapped. > ----------------------------------------------------------------------- > > Key: HBASE-10017 > URL: https://issues.apache.org/jira/browse/HBASE-10017 > Project: HBase > Issue Type: Bug > Components: mapreduce > Affects Versions: 0.94.6 > Reporter: Roman Nikitchenko > Priority: Critical > Attachments: HBASE-10017-r1544633.patch > > > Inside HRegionPartitioner class there is getPartition() method which should > map first numPartitions regions to appropriate partitions 1:1. But based on > condition last region is hashed which could lead to last reducer not having > any data. This is considered serious issue. > I reproduced this only starting from 16 regions per table. Original defect > was found in 0.94.6 but at least today's trunk and 0.91 branch head have the > same HRegionPartitioner code in this part which means the same issue. -- This message was sent by Atlassian JIRA (v6.1#6144)
