Ashutosh Chauhan commented on HIVE-6893:
----------------------------------------

Patch in current form eschews underlying problem. I think its worth spending time to figure out whats going on. FWIW, I have seen {{TestRetryingHMSHandler.testRetryingHMSHandler}} test fail on trunk with HiveQA runs with following trace:
{code}
org.apache.thrift.TApplicationException: create_database failed: out of sequence response
	at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:76)
	at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.recv_create_database(ThriftHiveMetastore.java:511)
	at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.create_database(ThriftHiveMetastore.java:498)
	at org.apache.hadoop.hive.metastore.HiveMetaStoreClient.createDatabase(HiveMetaStoreClient.java:534)
	at org.apache.hadoop.hive.metastore.TestRetryingHMSHandler.testRetryingHMSHandler(TestRetryingHMSHandler.java:76)
{code}

Above test failure which is independent of HS2 provides an independent repro test case. Though, in Hive QA runs it only fails rarely, hinting at some race condition.
