Review request for hive, Yongqiang He and Ning Zhang.
Summary (updated)
-------
I added a method called finishPerfLogger, which is called at the end of the run
method in Driver to allow PerfLogger subclasses to perform any cleanup tasks or
logging that requires all the perf stats to have been calculated. It takes as
parameters a Log, to be consistent with the other methods in PerfLogger, as
well as the QueryPlan from Driver in order to allow information such as the
query ID to be logged.
I should note that finishPerfLogger is not guaranteed to run. This was my
intention.
This addresses bug HIVE-2461.

Testing
-------
I created a subclass of PerfLogger which implemented the finishPerfLogger
method, and verified it was successfully called and executed.
I also ran some of the unit tests to verify nothing was broken.
Thanks,
