Changed the patch name. Set 2.8.0 to "Affects version" and "Fix version" when 
submitting failed due to unrelated unit test as mentioned above. And Leave them 
empty also does not works. The patch is generated based on branch-2.8. 
[~sidharta-s], Could you please tell me what I am missing here? Thanks

Zhankun Tang commented on YARN-5394:


The failed unit test "TestNMProxy" seems unrelated to this patch. I submited it 
with both "Affects version" and "target version" set to 2.8.0. Is this the 
reason causes "TestNMProxy" failure? *Or maybe I need to test it against trunk*?

I checked the code of the failed test case "testNMProxyRPCRetry" in branch-2.8. 
It seems that it should failed since no exception contains the expected string 
"Failed on local exception: java.net.SocketException". And in trunk, the same 
test case just assert the class type rather than string comparison.
{code:title=TestNMProxy.java(branch-2.8)}
try {
  proxy.startContainers(allRequests);
  Assert.fail("should get socket exception");
} catch (IOException e) {
  // socket exception should be thrown immediately, without RPC retries.
  Assert.assertTrue(e.toString().
  contains("Failed on local exception: java.net.SocketException"));
}
{code}

{code:title=TestNMProxy.java(trunk)}
try {
  proxy.startContainers(allRequests);
  Assert.fail("should get socket exception");
} catch (IOException e) {
  // socket exception should be thrown immediately, without RPC retries.
  Assert.assertTrue(e instanceof java.net.SocketException);
}
