> The code for each API in HiveMetaStore.java is like this:
> 1. openTransaction()
> 2. -- operation--
> 3. commit() or rollback() based on result of the operation.
> 4. add entry to notification log (unconditionally)
> If the operation is failed (in step 2), we still add entry to notification 
> log. Found this issue in testing.
> It is still ok as this is the case of false positive.
> If the operation is successful and adding to notification log failed, the 
> user will get an MetaException. It will not rollback the operation, as it is 
> already committed. We need to handle this case so that we will not have false 
> negatives.
