Qifan Chen has uploaded a new patch set (#5). ( http://gerrit.cloudera.org:8080/16474 )
Change subject: WIP IMPALA-10178 Run-time profile shall report skews ...................................................................... WIP IMPALA-10178 Run-time profile shall report skews This fix addresses the current limitation in runtime profile that skews existing in certain operators such as the rows read counter (RowsRead) are not directly reported. With the fix, any such skew is reported in the average counter profile. TODO: 1. Find out if RowsRead is really rows produced or rows processed. Rows processed is more relevant to skws; 2. Add rows processed counters for joins; 2. Add some unit tests for the skwe sections; 3. Run core tests.
