-----------------------------

             Summary: FullUpdateModifier does not handle alter table rename 
correctly
                 Key: SENTRY-2239
                 URL: https://issues.apache.org/jira/browse/SENTRY-2239
             Project: Sentry
          Issue Type: Bug
            Reporter: Na Li


When alter table rename changes DB name of the table, FullUpdateModifier 
changes all tables' DB name, not just the table whose name is changed.

This will change the table names incorrectly.

For example, when user changes table name from "db1.table1" to table name to 
"db2.table2" and in db1 there are two other tables: db1.table3, db1.table4, 
FullUpdateModifier changes the tables from "db1.table1, db1.table3, db1.table4" 
to "db2.table2, db2.table3, db3.table4". 

The desired behavior is changes the tables from "db1.table1" to "db2.table2". 
and "db1.table3, db1.table4" remains the same.
