I exploring a few options to setup kafka and I knew that the Zookeeper has to be up and running to initiate a kafka.
I would like to know how can I find the below.
1) hostname and port for my zookeeper instance---I checked the zoo.cfg and I could only find the ClientPort not the hostname, will hostname be the hostname of my box??
2) To check if ZooKeeper is up and running---I tried to do a ps -ef | grep "zoo" I could not find anything. May be I am using a wrong key word to search??
Any help would be really appreciated?

In order to perform ZooKeeper CLI operations, at very first we have to turn on our ZooKeeper server (“bin/zkServer.sh start”). Afterward, we will also turn on ZooKeeper client (“bin/zkCli.sh”). Hence, we can perform the following operation, once the client starts: Create znodes.
Start the ZooKeeper server before starting Application Builder. To start the ZooKeeper server on a Linux system, use the Zookeeper/zookeeper/bin/zkServer.sh restart command from your Watson Explorer installation directory. On Microsoft Windows systems, use the Zookeeper\zookeeper\bin\zkServer. cmd command.
To check if Zookeeper is accessible. One method is to simply telnet to the proper port and execute the stats command.
