-------------------------------------

             Summary: TestIPC timeouts occasionally
                 Key: HADOOP-9916
                 URL: https://issues.apache.org/jira/browse/HADOOP-9916
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Binglin Chang
            Assignee: Binglin Chang
            Priority: Minor


TestIPC timeouts occasionally, for example: 
[https://issues.apache.org/jira/browse/HDFS-5130?focusedCommentId=13749870&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13749870]
[https://issues.apache.org/jira/browse/HADOOP-9915?focusedCommentId=13753302&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13753302]

Look into the code, have not found the cause yet, but we can do something first:

1. there are two method with same name:
   void testSerial()
   void testSerial(int handlerCount, boolean handlerSleep, ...)
   the second is not a test case, but somehow it causes testSerial(first one) run two times, see test report:
{code}
  <testcase time="26.896" classname="org.apache.hadoop.ipc.TestIPC" name="testSerial"/>
  <testcase time="25.426" classname="org.apache.hadoop.ipc.TestIPC" name="testSerial"/>
{code}

2. timeout annotation should be added, so next time related log is available.
