      Description

      zkServer.sh output the PID of the zookeeper process with:
      echo -n $! > "$ZOOPIDFILE"

      This uses -n which sh's builtin echo does not support. From echo's manpage.
      <snip>
      Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does not accept
      the -n option. Consult the builtin(1) manual page.
      </snip>

      This means that echo -n PID > ZOOPIDFILE will mean the contents of ZOOPIDFILE will be "-n PID". This stops zkServer.sh stop from working correctly.
