Review request for hive, Peter Vary and Adam Szita.


Bugs: HIVE-18892
    https://issues.apache.org/jira/browse/HIVE-18892


Repository: hive-git


Description
-------

The TestExchangePartitions tests revealed that NPE is thrown if the 
exchange_partitions method is called with null, empty or non-existing DB and 
table names. These NPEs could be prevented with a simple null check and a 
MetaException with a proper error message should be thrown instead.
