Akira AJISAKA commented on MAPREDUCE-6579:
------------------------------------------

After YARN-3946, {{JobClient.getFailureInfo()}} returns the application master's diagnostic message. Therefore the following code fails:
{code}
      assertEquals( runningJob.getFailureInfo(),"");
{code}
I'm thinking the code can be replaced by
{code}
    String diag = runningJob.getFailureInfo();
    assertTrue(diag.startsWith(AMState.ACTIVATED) || diag.startsWith(AMState.ASSIGNED));
{code}
because the code intend to verify that the job is not failing.

By the way, the following javadoc is no longer correct. I'll update this.
{code:title=o.a.h.mapreduce.JobStatus}
   /**
    * Gets any available info on the reason of failure of the job.
    * @return diagnostic information on why a job might have failed.
    */
   public synchronized String getFailureInfo() {
     return this.failureInfo;
   }
{code}

Furthermore, I'd like to add a new method {{getDiagnostics}} to {{JobStatus}} and deprecate {{getFailureInfo}}. I'll create a separate jira for this.
