Tsuyoshi Ozawa commented on YARN-3798:
--------------------------------------
[~zxu] In the case of SessionMovedException, I think zk client should retry to
connect to another zk server with same session id automatically without
creating new session. If we create new session for SessionMovedException, we'll
face the same issue as Bibin and Varun reported. With new patch,
SessionMovedException is handled in same session. After we get
SessionMovedException, the zk client in ZKRMStateStore waits for passing
specified period and retrying operations. At that time, zk server should detect
the session has moved and close the client
as a document for ZooKeeper mentions:
http://zookeeper.apache.org/doc/r3.4.0/zookeeperProgrammers.html#ch_zkSessions
{quote}
When the delayed packet arrives at the first server, the old server detects
that the session has moved, and closes the client connection.
{quote}
If this behaviour is not same as described, we should fix ZooKeeper.
