Review request for hive and Paul Yang.


Changes
-------

Thanks for the feedback Paul.  I changed it to use host:port pairs instead of just hosts.


Summary
-------

I added a whitelist configuration variable, whose value should be a comma separated list of hosts.  A set of strings is created based on this list and the host name in a location given to a create/alter table/partition command to the HiveMetastore is compared to the values in that set.  If the list is nonempty, the table being altered/created or containing the partition is not external/non-native, and the location has an explicit host, the command is failed if the host is not in that set, otherwise the command continues as normal.


This addresses bug HIVE-2502.

Testing
-------

I used Thrift calls to test the following for each of the 4 commands create/alter table/partition:

Issuing the command with a location with a host that is not in the whitelist fails.
Issuing the command with a location with a host in the whitelist does not fail.


Thanks,

Kevin

> Add a whitelist of host names that can be checked before creating/altering a table/partition to verify that the location is acceptable.  The whitelist should be empty by default, and should be configurable.  The check should default to pass if there is no host in the location, or the whitelist is empty.
