      Description

      I have a situation where puppet is continually attempting to restart zookeeper. It appears as if /etc/init.d/zookeeper-server status returns the wrong answer in some cases. I can workaround this by setting the COLUMNS environment variable just before the ps in hadoop_is_process_alive().

      What is actually setting (or unsetting) this is a mystery, but I don't think its right for the init script to break.

      $ COLUMNS=80 ps -fp 2539 | grep 2539 | grep zookeeper >/dev/null ; echo $?
      1
      $ COLUMNS=1000 ps -fp 2539 | grep 2539 | grep zookeeper >/dev/null ; echo $?
      0
      

      It seems to me as if this method of using ps to check the daemon status is too fragile.
