> The TIP.isComplete(taskid) checks for TaskStatus.state being SUCCEEDED and this is used
to determine whether this taskid took the TIP to completion. Since, the taskstatus for a KILLED
task would have the state as KILLED, this check would fail and hence the TIP would never be
marked incomplete. The right solution is to maintain the successful taskid and use that in
TIP.isComplete(taskid). This bug got introduced in the last patch for HADOOP-1874.
