> 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.
