Arpit Agarwal updated HADOOP-10395:
-----------------------------------
Description:
{{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}
Although extremely unlikely it is possible for the queue to be intermittently
empty while the putters and getters are running. The assert can be coded
removed or coded differently.

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.
