Review Request: HIVE-2194: Add actions to MetaStoreEventListener to be performed on alter table and alter partition operations.

Review request for hive and Paul Yang.


Summary
-------

HIVE-2038 introduced the MetaStoreEventListener abstract class that defines actions to be performed after particular events on a metastore. Improve upon that class by adding events to be performed on "alter table" and "alter partition" actions.  Also, update the hive metastore to call the appropriate functions of the listeners when the events happen.


This addresses bug HIVE-2194.

Hi, is there any update on this?  Thanks for looking!

Thanks for your feedback, Carl.  I understand your point about the return value of those functions.  Is throwing a MetaException in the case of failure appropriate?

Furthermore, I noticed that a few other RawStore operations return boolean values, such as dropDatabase, alterDatabase, dropTable, addPartition, etc.  The return value in each case corresponds to successfully committing the transaction.  Should we adopt a uniform interface across these functions?

<https://reviews.apache.org/r/853/#comment1598>

    This method should either succeed or throw an exception. Since it already throws checked exceptions, adding a boolean return value makes things more complicated for the caller, and signals the same type of failure as an exception but without the ability to include information about what caused the failure. I think it would be better to modify the code so that an exception is always thrown when success==FALSE.
    
    This comment also applies to the various alterTable and alterPartition methods located in other classes.

The equals() method fails, because the parameter "transient_lastDdlTime" is sometimes off by one.  Otherwise, the two objects are entirely equal.  I think the db name, table name, and list of values also ensures equality.

The equals() method also fails here, even though the tables are logically equal.  In the case above, "tbl" does not have a PrincipalPrivilegeSet.  "oldTable" has a PrincipalPrivilegeSet, but all of it's fields are set to null.  This discrepancy comes from how we get the tables, but I think they should still be considered equal.
