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)
