Andras Bokor commented on YARN-8767:
------------------------------------
It seems if yarn.resourcemanager.address is not set
org.apache.hadoop.yarn.client.ClientRMProxy#getRMAddress will set the default
port which is 8032 but RM actually starts on somewhere around 50000.
We have to set "yarn.resourcemanager.address" for the job.
