Hi folks : My yarn jobs seem to be hanging in the "SHEDULED" state. I've restarted my nodemanager a few times , but no luck.
What are the possible reasons that YARN job submission hangs ? I know one is resource availability, but this is a fresh cluster on a VM with only one job, one NM, and one RM. 14/04/24 16:20:32 INFO ipc.Server: Auth successful for [email protected](auth:SIMPLE) 14/04/24 16:20:32 INFO authorize.ServiceAuthorizationManager: Authorization successful for [email protected] (auth:KERBEROS) for protocol=interface org.apache.hadoop.yarn.api.ApplicationClientProtocolPB 14/04/24 16:20:32 INFO resourcemanager.ClientRMService: Allocated new applicationId: 4 14/04/24 16:20:33 INFO resourcemanager.ClientRMService: Application with id 4 submitted by user yarn 14/04/24 16:20:33 INFO resourcemanager.RMAuditLogger: USER=yarn IP=192.168.122.100 OPERATION=Submit Application Request TARGET=ClientRMService RESULT=SUCCESS APPID=application_1398370674313_0004 14/04/24 16:20:33 INFO rmapp.RMAppImpl: Storing application with id application_1398370674313_0004 14/04/24 16:20:33 INFO rmapp.RMAppImpl: application_1398370674313_0004 State change from NEW to NEW_SAVING 14/04/24 16:20:33 INFO recovery.RMStateStore: Storing info for app: application_1398370674313_0004 14/04/24 16:20:33 INFO rmapp.RMAppImpl: application_1398370674313_0004 State change from NEW_SAVING to SUBMITTED 14/04/24 16:20:33 INFO fair.FairScheduler: Accepted application application_1398370674313_0004 from user: yarn, in queue: default, currently num of applications: 4 14/04/24 16:20:33 INFO rmapp.RMAppImpl: application_1398370674313_0004 State change from SUBMITTED to ACCEPTED 14/04/24 16:20:33 INFO resourcemanager.ApplicationMasterService: Registering app attempt : appattempt_1398370674313_0004_000001 14/04/24 16:20:33 INFO attempt.RMAppAttemptImpl: appattempt_1398370674313_0004_000001 State change from NEW to SUBMITTED 14/04/24 16:20:33 INFO fair.FairScheduler: Added Application Attempt appattempt_1398370674313_0004_000001 to scheduler from user: yarn 14/04/24 16:20:33 INFO attempt.RMAppAttemptImpl: appattempt_1398370674313_0004_000001 State change from SUBMITTED to SCHEDULED -- Jay Vyas http://jayunit100.blogspot.com
