Subject [jira] [Created] (YARN-4916) TestNMProxy.tesNMProxyRPCRetry fails
Date Sat, 02 Apr 2016 19:51:25 GMT
Tibor Kiss created YARN-4916:
--------------------------------

             Summary: TestNMProxy.tesNMProxyRPCRetry fails
                 Key: YARN-4916
                 URL: https://issues.apache.org/jira/browse/YARN-4916
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.6.4, 3.0.0, 2.8.0, 2.7.3
         Environment: OS X 10.11 with Oracle JDK 1.7.0_79
Windows Server 2012 with Oracle JDK 1.7.0_79
            Reporter: Tibor Kiss


The test ensures that java.net.SocketException is thrown from
NMProxy.startContainers() without the RPC Request being retried.

With Oracle JDK 1.7 on OS X & Windows BindException is thrown from startContainers().
The testcase expects that SocketException is thrown - which is BindException's superclass.
The exception type check is implemented using string compare and not reflection, therefore
the thrown BindException is not accepted.
