> The patch of HIVE-6734 added some DDL writetypes and checked DDL writetype in DbTxnManager.java.
> We use DummyTxnManager as the default value of hive.txn.manager in hive-site.xml. We
noticed that the operation of CREATE TEMPORARY FUNCTION has a DLL_NO_LOCK writetype but it
requires a EXCLUSIVE lock. If we try to create a temporary function while there's a SELECT
is processing at the same database, then the console will print 'conflicting lock present
for default mode EXCLUSIVE' and the CREATE TEMPORARY FUNCTION operation won't get the lock
until the SELECT is done. Maybe it's a good idea to check the DDL's writetype in DummyTxnManager
too.
