FAQ
Hi,

I am not sure if this is the right group for yarn, if so please let me know.

I have setup Yarn ha cluster, with 2 rm server and 3 nm. The HA
configuration looks ok and all services started successfully. I can see the
rmstore being created in zookeeper

But when I try to submit a job it just tries to connect to the server as
below and never ends.

Is there anything I am missing? Do i have to specifically configure
anything in yarn-site.xml via the CM?
