Rajesh Balamohan updated TEZ-2137:
----------------------------------
Attachment: TEZ-2137.2.patch
Revising the patch post TEZ-2001. Added the following counters which provide
absolute timestamps. Absolute timestamps are needed when we need to analyze
the details at vertex levels.
-SORTER_FLUSH_START_TIME : Absolute time for the sorter to start flush()
-SORTER_FINAL_MERGE_START_TIME : Absolute time for the sorter to start final
merge. In case final merge is disabled, this counter would not be populated.
-SORTER_FLUSH_END_TIME : Absolute time for the sorter to finish flushing the
data for final result.
Need to add test case to TestDefaultSorter/TestPipelinedSorter after TEZ-2198
gets committed.
