I just set up ResourceManager HA. Both of the resourcemanagers started
correctly. When I killed the active one, the other became active. But when I
used the following command to do a manual failover, I got exceptions. I don't
know what cause this problem. Could anyone help me ? Many Thanks!
Command:
yarn rmadmin -failover rm1 rm2
Exceptions:
Exception in thread "main" java.lang.UnsupportedOperationException:
RMHAServiceTarget doesn't have a corresponding ZKFC address
