ZooKeeper was not started.
Ensure that the ZooKeeper clientPort is available, the STREAMS_INSTALL environment variable is set, and the user has write permission to the ZooKeeper dataDir directory. If the home directory is on a shared file system, ensure that ZooKeeper is not started on a different host. Check for errors in application traces, and ZooKeeper logs located in the directory specified by the bootstrap property ''streams.zookeeper.logDir''.
