Siddharth Seth commented on TEZ-2119:
-------------------------------------

[~rohini] - there may be another similar jira, possibly filed by you :) I'll link it if I can find it.
+1 for adding these today, and container re-use counters per dag.

> It would be very nice to have TOTAL_LAUNCHED_CONTAINERS counter added to this. The difference between TOTAL_LAUNCHED_CONTAINERS and TOTAL_LAUNCHED_TASKS should make it easy to see how much container reuse is happening. It is very hard to find out now.
