Distinguish between 'failed' and 'killed' tips
----------------------------------------------
Key: HADOOP-1321
URL: https://issues.apache.org/jira/browse/HADOOP-1321
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.12.3
Reporter: Arun C Murthy
Assigned To: Arun C Murthy
When a 'tip' fails since more than MAX_TASK_FAILURES are exceeded, the tip is
marked 'killed' and 'failed' (via a call to TaskInProgress.kill from
JobInProgress.incompleteSubTask) which makes it hard to distinguish from
'killed' tips (since for e.g. the job itself got killed).
Straight-forward fix is to add a TaskInProgress.fail() and use that instead.
