task tracker ghosts remain after 10 minutes
-------------------------------------------
Key: HADOOP-179
URL: http://issues.apache.org/jira/browse/HADOOP-179
Project: Hadoop
Type: Bug
Components: mapred
Versions: 0.1.1
Reporter: Owen O'Malley
Assigned to: Owen O'Malley
I had a bunch of TaskTrackers time out because they were in the middle of job
cleanup and the JobTracker restarted them by responding to emitHeartbeat with
UNKNOWN_TASKTRACKER. Afterwards, I ended up with both the new and the restarted
TaskTrackers on the list:
node1100_1234, 0-10 seconds since heartbeat
node1100_4321, >10,000 seconds since heartbeat
