Janaki Lahorani updated HIVE-17832:
-----------------------------------
Description: hive.metastore.disallow.incompatible.col.type.changes when set
to true, will disallow incompatible column type changes through alter table.
But, this parameter is set system wide, and changing it requires restart of
HMS. The default value of this parameter is true. User can set the parameter
to false and change the column type through alter if this can be modified
within a session.
