Daniel Dai commented on PIG-4868: --------------------------------- This only applicable for the vertex with input, right? If so, +1. > bytes.per.reducer configured by user not honored in Tez > ------------------------------------------------------- > > Key: PIG-4868 > URL: https://issues.apache.org/jira/browse/PIG-4868 > Project: Pig > Issue Type: Bug > Reporter: Rohini Palaniswamy > Assignee: Rohini Palaniswamy > Attachments: PIG-4868-1.patch > > > We don't use that in parallelism estimation and only use that in > ShuffleVertexManager. Usually it is fine, but in cases when user has set a > really low bytes.per.reducer it does not work as our estimation is low. > ShuffleVertexManager only decreases parallelism and not increases parallelism. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
