Scenario: I have an org.apache.hadoop.mapreduce.Job that has just finished. I want to get information about the completed tasks within that job, particularly the ones that failed. I tried calling getTaskCompletionEvents and getTaskReports, and they both always return an empty list. Also, getStatus().getFailureInfo() returns "NA" even if the job failed. The job counters are still available, so I know the job hasn't been retired. Am I missing something?
This is Hadoop 2.7.3. Right now, I'm running it in local mode, but the production system runs on Amazon EMR. Thanks. -MB
