--------------------------------------
Summary: TestCallQueueManager is flaky
Key: HADOOP-10395
URL: https://issues.apache.org/jira/browse/HADOOP-10395
Project: Hadoop Common
Issue Type: Bug
Components: test
Affects Versions: 2.4.0
Reporter: Arpit Agarwal
{{TestCallQueueManager#testSwapUnderContention}} fails occasionally on a test
VM with this assert.
{code}
java.lang.AssertionError: null
at org.junit.Assert.fail(Assert.java:92)
at org.junit.Assert.assertTrue(Assert.java:43)
at org.junit.Assert.assertTrue(Assert.java:54)
at
org.apache.hadoop.ipc.TestCallQueueManager.testSwapUnderContention(TestCallQueueManager.java:193)
{code}
I think the issue is that the assert is probabilistic and although extremely
unlikely it is possible for the queue to be intermittently empty while the
putters and getters are running.
