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)
