On our worker nodes, I see repeated requests for KillJobActions for the same old job: 2010-01-31 00:00:01,024 INFO org.apache.hadoop.mapred.TaskTracker: Received 'KillJobAction' for job: job_201001261532_0690 2010-01-31 00:00:01,064 WARN org.apache.hadoop.mapred.TaskTracker: Unknown job job_201001261532_0690 being deleted.
This request and response is repeated almost 30k times over the course of the day. Other nodes have the same behavior, except with different job ids. The jobs presumably all ran in the past, to completion or got killed manually. We use the grid fairly actively and that job is several hundred increments old. Has anyone seen this before? Is there a way to stop it?
