------------------------------------
Summary: Improve the stability of TestNotificationListener
Key: HIVE-14960
URL: https://issues.apache.org/jira/browse/HIVE-14960
Project: Hive
Issue Type: Bug
Components: Test
Affects Versions: 2.1.0
Reporter: Marta Kuczora
Assignee: Marta Kuczora
Priority: Minor
The TestNotificationListener.testAMQListener test case fails occasionally with
the following error:
{noformat}
Error Message
expected:<[CREATE_DATABASE, CREATE_TABLE, ADD_PARTITION, ALTER_PARTITION,
DROP_PARTITION, ALTER_TABLE, DROP_TABLE, DROP_DATABASE]> but
was:<[CREATE_DATABASE, CREATE_TABLE, ADD_PARTITION, ALTER_PARTITION,
DROP_PARTITION, ALTER_TABLE, DROP_TABLE]>
Stacktrace
java.lang.AssertionError: expected:<[CREATE_DATABASE, CREATE_TABLE,
ADD_PARTITION, ALTER_PARTITION, DROP_PARTITION, ALTER_TABLE, DROP_TABLE,
DROP_DATABASE]> but was:<[CREATE_DATABASE, CREATE_TABLE, ADD_PARTITION,
ALTER_PARTITION, DROP_PARTITION, ALTER_TABLE, DROP_TABLE]>

{noformat}
This error can happen if the testAMQListener method is completed before the
last DROP_TABLE message got processed and put to the actualMessages list by the
onMessage method. This can happen if there is a small delay in receiving the
message, since the message receiving is not synchronized with the
testAMQListener method.
