It will be useful if we have {code} SLOTS_MILLIS_REDUCES_COPY SLOTS_MILLIS_REDUCES_SORT SLOTS_MILLIS_REDUCES_REDUCE {code} which measures three different phases of a reducer. This will help us identify the bottleneck of the reducers. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
