Review comment:
yes, we have double counted the metrics of api calling by the
startFunction and the PerfLogger, e.g, the total call count and the active
count of the api.

Review comment:
Thanks a lot for the feedback! you are right, this is where may break
compatibility, including the MetaStoreEndFunctionContext(we cannot retrieve
inputTableName by method `getInputTableName()` any more). I not so sure if we
can make such changes though this can help clean some codes...

Review comment:
Not a bug really, just to clean up the codes. The following pieces of
codes can be simply treated as `lhsValues.equals(rhsValues)` by `equals` of an
ArrayList.
if (lhsValues.size() != rhsValues.size()) {
return false;
}
for (int i=0; i<lhsValues.size(); ++i) {

Make sense, let me take a look. Thank you!

> Some start/end functions are incomplete or wrong in the HMSHandler, these
> functions audit actions, monitor the performance, and notify the end function
> listeners. We have already measured the performance of the HMSHandler in
> PerfLogger, and covered more methods than these functions that have done, so
> we can remove the monitoring from the start/end functions, move the end
> function listeners to the RetryingHMSHandler to eliminate the try-finally
> blocks that spread across many different methods. After these, we can try to
> cleanup the functions to make HMSHandler be more simplified.
