Hi All. Facing a very weird issue, wherein the command
*/etc/init.d/cassandra start* causes cassandra to start when the command is run from command-line. However, if I put the above as a cron job ** * * * * /etc/init.d/cassandra start* cassandra never starts. I have checked, and "cron" service is running. Any ideas what might be wrong? I am pasting the cassandra script for brevity. Thanks and Regards, Ajay #################################################################################################### #! /bin/sh ### BEGIN INIT INFO # Provides: cassandra # Required-Start: $remote_fs $network $named $time # Required-Stop: $remote_fs $network $named $time # Should-Start: ntp mdadm # Should-Stop: ntp mdadm # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: distributed storage system for structured data # Description: Cassandra is a distributed (peer-to-peer) system for # the management and storage of structured data. ### END INIT INFO # Author: Eric Evans <eev...@racklabs.com> DESC="Cassandra" NAME=cassandra PIDFILE=/var/run/$NAME/$NAME.pid SCRIPTNAME=/etc/init.d/$NAME CONFDIR=/etc/cassandra WAIT_FOR_START=10 CASSANDRA_HOME=/usr/share/cassandra FD_LIMIT=100000 [ -e /usr/share/cassandra/apache-cassandra.jar ] || exit 0 [ -e /etc/cassandra/cassandra.yaml ] || exit 0 [ -e /etc/cassandra/cassandra-env.sh ] || exit 0 # Read configuration variable file if it is present [ -r /etc/default/$NAME ] && . /etc/default/$NAME # Read Cassandra environment file. . /etc/cassandra/cassandra-env.sh if [ -z "$JVM_OPTS" ]; then echo "Initialization failed; \$JVM_OPTS not set!" >&2 exit 3 fi export JVM_OPTS # Export JAVA_HOME, if set.
