Kuhu Shukla updated TEZ-3605: ----------------------------- Attachment: TEZ-3605.012.patch Fixing the numspill=0 case for DefaultSorter to honor sendPartitionDetails flag. > Detect and prune empty partitions for the Ordered case > ------------------------------------------------------ > > Key: TEZ-3605 > URL: https://issues.apache.org/jira/browse/TEZ-3605 > Project: Apache Tez > Issue Type: Bug > Reporter: Kuhu Shukla > Assignee: Kuhu Shukla > Attachments: TEZ-3605.001.patch, TEZ-3605.002.patch, > TEZ-3605.003.patch, TEZ-3605.004.patch, TEZ-3605.005.patch, > TEZ-3605.006.patch, TEZ-3605.007.patch, TEZ-3605.008.patch, > TEZ-3605.009.patch, TEZ-3605.010.patch, TEZ-3605.011.patch, TEZ-3605.012.patch > > > Analogous to the Unordered case we should not have empty partition > entries/segments in the Ordered/DefaultSorter case. This will save writing > unnecessary data. > Additionally, with tez_shuffle feature (TEZ-3334), in a heavily auto reduced > job, this change would allow not fetching empty partitions and then throwing > them away. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
