Olga Natkovich commented on PIG-1617: ------------------------------------- Looks good. +1 > 'group all' should always use one reducer > ----------------------------------------- > > Key: PIG-1617 > URL: https://issues.apache.org/jira/browse/PIG-1617 > Project: Pig > Issue Type: Improvement > Affects Versions: 0.8.0 > Reporter: Thejas M Nair > Assignee: Thejas M Nair > Fix For: 0.8.0 > > Attachments: PIG-1617.1.patch > > > 'group all' sends all rows to a single reducer, it does not make sense to > spawn more than one reducer for it. But if higher value of parallelism is > specified or if the input is large enough so that changes in PIG-1249 result > in larger value being set, there are additional reducers spawned that don't > do anything useful. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
