Unable to schedule falcon process - Could not perform authorization operation, java.io.IOException: Couldn't set up IO streams

Question

​Hi, I am trying to schedule a falcon process using falcon CLI and falcon service user on a Kerberised cluster. I am getting the following error message:

ERROR: Bad Request;default/org.apache.falcon.FalconWebException::org.apache.falcon.FalconException: Entity schedule failed for process: testHiveProc

Falcon app logs shows following:

used by: org.apache.falcon.FalconException: E0501 : E0501: Could not perform authorization operation, Failed on local exception: java.io.IOException: Couldn't set up IO streams; Host Details :

Any suggestions? Thanks.

Answer 1

Root cause: Oozie was running out of processes due to more number of scheduled jobs.

Short term solution: Restart Oozie server

Long term solution: - Increase ulimit - Limit the number of scheduled jobs in Oozie
