> Occasionally, the test TestColumnEndToEnd.testCrossDbTableOperations fails at statement
>  statement.execute("CREATE table db_1.t1 as select tb1.id, tb3.val, tb2.num from db_1.tb1,db_2.tb3,db_2.tb2");
>  We should make it stable to avoid blocking other updates.
> More info:
> 1) Failed run with the following statement. The reason it fails is not related to sentry
processing. It is due to the map reduce task fails with the more complicated join in the
unit test
