Michi Mutsuzaki commented on ZOOKEEPER-1905:
--------------------------------------------
Isn't the client supposed to queue requests while it's trying to connect to the
server?
> ZKClients are hitting KeeperException$ConnectionLossException due to wrong
> usage pattern

> Key: ZOOKEEPER-1905
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1905
> Project: ZooKeeper
> Issue Type: Sub-task
> Components: tests
> Reporter: Rakesh R
> Assignee: Rakesh R
> Fix For: 3.4.7
>
>
> Since the ZooKeeper client connection establishment happens in async way, the
> client should wait for the 'KeeperState.SyncConnected' event before start
> performing any ops. Many tests are having this kind of wrong pattern.
