Chandni Singh commented on YARN-7470:
-------------------------------------
For recovery test, the NM needs to connect to RM using RPC which required using
fixed ports. When the port is already in use, then the test fails with
BindException. There was an existing util {{HATestUtil}} which finds a free
port (given a base port) and sets the Rpc address for RM, so I added that to
the test.
[~jianhe] could you please review?
