Log:
Fixing bug in removing ProtectMode from a Table
(Bhushan Mandhani via Carl Steinbach)
Summary:
When ProtectMode has every member set to the default false value, the toString() method returns null. When this happens, we should realize that the PROTECT_MODE parameter is
no longer needed and should be removed for the Table or Partition. Currently, we try to persist this null value and get an error.
Test Plan: Ran Hive. Checked that "alter table some_table disable NO_DROP CASCADE" successfully removed the PROTECT_MODE parameter and did not give any error. Running unit tests.
