> Many ZooKeeper tests are flaky because they proceed with zk operation without
> connecting to ZooKeeper server.
> Recently in our build
> {{org.apache.zookeeper.server.ZooKeeperServerMainTest.testStandalone()}}
> failed.
> After analyzing we found that it is failed because it is not waiting for
> ZooKeeper client get connected to server. In this case normally zookeeper
> client gets connected immediately but if not connected immediately the test
> case is bound to fail.
> Not only ZooKeeperServerMainTest but there are many other classes which have
> such test cases. This jira is to address all those test cases.
