Guys, Have struggled for the last four days with this and still cannot find an answer even after hours of searching the web.
I tried oozie workflow to execute my consecutive sqoop jobs in parallel. I use forking that executes 9 sqoop-action-nodes. I had no problem executing the job on a pseudo-distributed cluster but with an added DN/TT node I ran into (what seems like) deadlocking. Oozie web interface displays those jobs as "Running" indefinitely until I eventually kill the workflow. What I did noticed wasd that if I was to reduce the number of sqoop-action-nodes to 3, all works fine. I found somewhere about oozie.service.CallableQueueService.callable.concurrency property to be set by default to 3 and it hinted me that this must be it them. I tried to over-ride this property by increasing this number to 5 in oozie-site.xml and restart oozie server and then run 4 sqoop-action-nodes in fork but the result is the same. 2 out of 4 nodes execute successfully (not in the same order every time) but the other 2 get hung in indefinite "Running...". There were some suggestion about changing queue name from default but nothing was clear as to what it change it to and where. In case someone found a solution to this please do share. I will greatly appreciate it. Thanks, AK47 NOTICE: This e-mail message and any attachments are confidential, subject to copyright and may be privileged.
