Sheng Wang commented on SINGA-153:
----------------------------------
It seems that zookeeper process is not launched properly.
You can use "netstat -ntlp" to check if port 2181 (default zk port) is being
monitored.
One way to check the error is directly go to $zookeeper$/bin directory and run
command "zkServer.sh start"
You will see the error details then.
One possible error might be no permission for creating zookeeper folder under
/tmp/zookeeper.
In this case, you can manually create the folder.
