Vihang Karajgaonkar commented on HIVE-19752:
--------------------------------------------

Ah, I see. Thanks [~stakiar] LGTM +1 On a side note, I am curious to understand the behavior
of Metrics scope when there are exceptions and we don't call the {{PerfLogEnd}}. I hope we
don't leak them.

> There are several areas where Hive performs a lot of S3 operations, it would be good
to add PerfLogger statements around this so we can measure how long they take.
