Review request for hive and Paul Yang.
Summary
-------
Every failure in an alter table function always return a MetaException. When
altering tables and catching exceptions, we throw a MetaException in the
"finally" part of a try-catch-finally block, which overrides any other
exceptions thrown.
This patch moves the code to throw an error on a commit failure outside of the
try-catch-finally block. So any errors within the try block are thrown
properly. Only when success == false will we throw a MetaException.
This addresses bug HIVE-2338.

Testing
-------
Tested failing alter table metastore commands; they threw
InvalidOperationExceptions as they should, instead of meaningless
MetaExceptions.
Thanks,
