         Environment: linux

If the resource manager is restarted while the job execution is in progress, the job is getting hanged.
UI shows the job as running.
In the RM log, it is throwing an error "ERROR org.apache.hadoop.yarn.server.resourcemanager.ApplicationMasterService: AppAttemptId doesnt exist in cache appattempt_1318579738195_0004_000001"
In the console MRAppMaster and Runjar processes are not getting killed
