java - Getting list of tasks from Hadoop Job object -


using hadoop 2.7.3.

i'm trying information on specific tasks freshly completed hadoop job. specifically, tasks failed, if any. tried both gettaskcompletionevents , gettaskreports - both of methods return empty list, regardless of job's exit status. causing this?

alternately: there other way information failed tasks? is, if task attempt fails due exception, how exception?
