else if ("-events".equals(argv[i])) {
        listEvents(argv[i+1], Integer.parseInt(argv[i+2]), 
                   Integer.parseInt(argv[i+3]));
        i += 3;
      }

So incomplete args to

$ bin/hadoop job -events job_0001

could be the reason for the ArrayIndexOutOfBoundsException you noticed? *smile* > TaskTracker falls into an infinite loop. > ---------------------------------------- > > Key: HADOOP-1374 > URL: https://issues.apache.org/jira/browse/HADOOP-1374 > Project: Hadoop > Issue Type: Bug > Components: mapred > Affects Versions: 0.12.3 > Reporter: Konstantin Shvachko > Assigned To: Arun C Murthy > Fix For: 0.13.0 > > > All maps had been completed successfully.
