# BIGTOP-2742:
# The default zeppelin PIDFILE includes the literal $(hostname) string, which is carried into the init script's pidfile declaration.
# But pidfile does not subshell out to generate the expected string.
# The zeppelin process does indeed start up, but systemctl reports a failure because it's looking for a non-existent pidfile.
#
# Workaround:
#   Remove unnecessary $HOSTNAME from zeppelin-daemon.sh and also make the same adjustment to zeppelin.svc.
# TODO:
#   Request the issue to zeppelin upstream, If accepted, remove this workaround.
