Не удалось запустить процесс как службу? (код = выход, статус = 203 / EXEC)

Мне нужно запустить процесс Кассандры как службы. Для этого поместите следующий скрипт в каталог /etc/init.d согласно doc

, так что вот мой скрипт, который я поместил в каталог init. 

#!/bin/bash
# chkconfig: 2345 99 01
# description: Cassandra

. /etc/rc.d/init.d/functions

CASSANDRA_HOME=/home/cassandra/binaries/cassandra
CASSANDRA_BIN=$CASSANDRA_HOME/bin/cassandra
CASSANDRA_NODETOOL=$CASSANDRA_HOME/bin/nodetool
CASSANDRA_LOG=$CASSANDRA_HOME/logs/cassandra.log
CASSANDRA_PID=$CASSANDRA_HOME/cassandra.pid
CASSANDRA_LOCK=$CASSANDRA_HOME/cassandra.lock
PROGRAM="cassandra"

if [ ! -f $CASSANDRA_BIN ]; then
  echo "File not found: $CASSANDRA_BIN"
  exit 1
fi

RETVAL=0

start() {
  if [ -f $CASSANDRA_PID ] && checkpid `cat $CASSANDRA_PID`; then
    echo "Cassandra is already running."
    exit 0
  fi
  echo -n $"Starting $PROGRAM: "
  $CASSANDRA_BIN -p $CASSANDRA_PID -R >> $CASSANDRA_LOG 2>&1
  sleep 60
  RETVAL=$?
  if [ $RETVAL -eq 0 ]; then
    touch $CASSANDRA_LOCK
    echo_success
  else
    echo_failure
  fi
  echo
  return $RETVAL
}

stop() {
  if [ ! -f $CASSANDRA_PID ]; then
    echo "Cassandra is already stopped."
    exit 0
  fi
  echo -n $"Stopping $PROGRAM: "
#  $CASSANDRA_NODETOOL -h 127.0.0.1 decommission
  if kill `cat $CASSANDRA_PID`; then
    RETVAL=0
    rm -f $CASSANDRA_LOCK
    echo_success
  else
    RETVAL=1
    echo_failure
  fi
  echo
  [ $RETVAL = 0 ]
}

status_fn() {
  if [ -f $CASSANDRA_PID ] && checkpid `cat $CASSANDRA_PID`; then
    echo "Cassandra is running."
    exit 0
  else
    echo "Cassandra is stopped."
    exit 1
  fi
}

case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  status)
    status_fn
    ;;
  restart)
    stop
    start
    ;;
  *)
    echo $"Usage: $PROGRAM {start|stop|restart|status}"
    RETVAL=3
esac

exit $RETVAL

Однако при выполнении service cassandra start это вылилось в ошибку следующим образом. 

[root@casstestnode1 init.d]# service cassandra start
Starting cassandra (via systemctl):  Job for cassandra.service failed because the control process exited with error code. See "systemctl status cassandra.service" and "journalctl -xe" for details.

и 

[root@casstestnode1 init.d]# systemctl status cassandra.service

Я перезагружаю ВМ и повторяю попытку еще раз, но ошибка остается той же. Любой эксперт по Linux, пожалуйста, помогите.

Кроме того, здесь выводится файл journalctl -xe 

[root@casstestnode1 init.d]# journalctl -xe
