Kenji Kikushima created YARN-1911:
-------------------------------------

             Summary: NullPointerException in ResourceOption.getOverCommitTimeout()
                 Key: YARN-1911
                 URL: https://issues.apache.org/jira/browse/YARN-1911
             Project: Hadoop YARN
          Issue Type: Bug
          Components: api
    Affects Versions: 2.3.0
            Reporter: Kenji Kikushima


I'm trying to implement REST API for Dynamic configuration. But NullPointerException occurred
when ResourceOption.getOverCommitTimeout() called. Here is a sample code with error message.

{code}
@Test
public void testGetOverCommitTimeout() {
  Resource capability = Resource.newInstance(4096, 4);
  ResourceOption resourceOption = ResourceOption.newInstance(capability,
    RMNode.OVER_COMMIT_TIMEOUT_MILLIS_DEFAULT);
  Assert.assertEquals(RMNode.OVER_COMMIT_TIMEOUT_MILLIS_DEFAULT,
    resourceOption.getOverCommitTimeout());
}
{code}

{code}
