Hi @Veerendra Nath Jasthi I've tried this myself just now, by first exporting the current settings like so; curl -X GET -H 'Content-Type: application/json' http://nifibox:9090/nifi-api/processors/6391462d-0166-1000-0000-000002b215e0 | python -m json.tool > /tmp/processorconfig.json And then from the resulting json output, I modify the directory listed and post it back like so; curl -X PUT -H 'Content-Type: application/json' http://nifibox:9090/nifi-api/processors/6391462d-0166-1000-0000-000002b215e0 -d @processorconfig.json BTW, specifying the processor ID alone on the PUT operation is enough - even if the processor is part of a different process group the above example still works. ...

Hi @Sai Krishna Makineni There isn't really any option for oozie to run against a specific host, the only option you would have in Oozie to execute on a specific host is with the SSH Action Extension; The ssh action starts a shell command on a remote machine as a remote secure shell in background. The workflow job will wait until the remote shell command completes before continuing to the next action. The shell command must be present in the remote machine and it must be available for execution via the command path.
