QuorumPeerMainTest.testQuorum, testBadPackets are failing intermittently
------------------------------------------------------------------------
Key: ZOOKEEPER-1414
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1414
Project: ZooKeeper
Issue Type: Test
Components: server
Affects Versions: 3.4.3, 3.5.0
Reporter: Rakesh R
Priority: Minor
The QuorumPeerMainTest.testQuorum, testBadPackets testcases are failing
intermittently due to the wrong ZKClient usage pattern.
Saw the following ConnectionLoss on 3.4 version:
{noformat}
KeeperErrorCode = ConnectionLoss for /foo_q1
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode =
ConnectionLoss for /foo_q1
at org.apache.zookeeper.KeeperException.create(KeeperException.java:90)
at org.apache.zookeeper.KeeperException.create(KeeperException.java:42)
at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:657)

org.apache.zookeeper.server.quorum.QuorumPeerMainTest.testBadPackets(QuorumPeerMainTest.java:212)
{noformat}
Since the ZooKeeper connection is happening in async way through ClientCnxn,
the client should wait for the 'KeeperState.SyncConnected' event before start
using. But these test cases are not waiting for the connection like:
{noformat}
ZooKeeper zk = new ZooKeeper("127.0.0.1:" + CLIENT_PORT_QP1,
ClientBase.CONNECTION_TIMEOUT, this);
zk.create("/foo_q1", "foobar1".getBytes(), Ids.OPEN_ACL_UNSAFE,
CreateMode.PERSISTENT);
{noformat}
