> In DummyTxnManager [line 163 | http://grepcode.com/file/repo1.maven.org/maven2/co.cask.cdap/hive-exec/0.13.0/org/apache/hadoop/hive/ql/lockmgr/DummyTxnManager.java#163], it always locks the current database.
> That is not correct since the current database can be "db1", and the query can be "select * from db2.tb1", which will lock db1 unnecessarily.
