How to set the jobTracker hostname and port in Hue Oozie Dashboard.
By default Hue will run Oozie workflows using "localhost:8032" as the jobTracker address and port:
If Yarn is using a non-standard port or Yarn is located on a different node than Oozie the workflow will fail with:
org.apache.oozie.action.ActionExecutorException: JA006: Call From huenode.domain.com/10.19.10.179 to localhost:8032 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
1. Log into Ambari
2. Select the YARN service
3. Review the value for configuration setting: "yarn.resourcemanager.address" under "Advanced yarn-site", in this example we assume the value is : "RMNode.domain.com:8050"
4. Locate the hue.ini configuration file, which will likely be in one of these three locations:
5. Open hue.ini and add in two entries to define the address and port to use for the resource manager as per the example below.
# Enter the host on which you are running the ResourceManager
# The port where the ResourceManager IPC listens on
6. Restart HUE by running:
sudo /etc/init.d/hue restart
7. Test the workflow.
