Using HDP Sandbox 2.0, Hyper-V, static IP
I have a MapReduce Java program which runs OK at the command line. However, when running it as a map-reduce action in an oozie workflow, the job is always stuck at RUNNING status. Killing the job (by oozie job -kill <JobID>), after a long while (may be 30 minutes) the oozie web console http://sandbox.hortonworks.com:11000/oozie/ finally shows the job as KILLED. I could then review the job log ans saw this exception:
[quote]Error starting action [MaxTemperatureMR]. ErrorType [TRANSIENT], ErrorCode [ JA006], Message [ JA006: Call From sandbox.hortonworks.com/192.168.1.72 to sandbox.hortonworks.com:50030 failed on connection exception: java.net.ConnectException: Connection refused;[/quote]
I am confident that the oozie workflow XML definition is OK. The properties file used to configured the job contains:
I am not sure what value I should use for jobTracker, I have tried local, sandbox.hortonworks.com:8021, sandbox.hortonworks.com:50030, sandbox.hortonworks.com:50300. All failed by the same error.
Hope you can help guide me toward a solution.
