@harishreedharan the details are in the linked issue and I tried on two
different setups. Are you sure you are using "--master yarn-cluster" as it does
work with "--master yarn-client"? Note the trace below wit specific attention
to "RMDelegationTokenSelector" not being able to find a delegation token and
thus failing to connect. I *am* surprised no-one else has encountered this as
including the delegation token seems pretty standard stuff (and yet it wasn't
done).
