Description

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.

@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());
}
