      Description

      If ZooKeeper is started with zkServer.sh, and an error is shown that a ZooKeeper process is already running, the command returns with an exit status of 0, while it should end with a non-zero exit status.

      Example:
      $ bin/zkServer.sh start
      JMX enabled by default
      Using config: /home/reed/zookeeper/bin/../conf/zoo.cfg
      Starting zookeeper ... already running as process 25063.
      $ echo $?
      0

      This can make it difficult for automated scripts to check if creating a new ZooKeeper process was successful, as it won't catch if a user accidentally started it before.
