zhihai xu commented on YARN-3798:
---------------------------------
I think we should also create a new session for SessionMovedException.
We hit the SessionMovedException before, the following is the reason for the
SessionMovedException we find:
# ZK client tried to connect to Leader L. Network was very slow, so before
leader processed the request, client disconnected.
# Client then re-connected to Follower F reusing the same session ID. It was
successful.
# The request in step 1 went into leader. Leader processed it and invalidated
the connection created in step 2. But client didn't know the connection it used
is invalidated.
# Client got SessionMovedException when it used the connection invalidated by
leader for any ZooKeeper operation.
IMHO, the only way to recover from this error at RM side is to take
SessionMovedException as SessionExpiredException, close current ZK client and
create a new one.
