Re: Starting cassandra with -D option
Idea is to avoid having the copies of cassandra code in each node, If you run cassandra from the NAS you are adding a single point of failure into the system. Better to use some form of deployment automation and install all the requirement components onto each node.

Re: Starting cassandra with -D option
I did something similar for my installation, but I used ENV variables: I created a directory on a machine (call this the master) with directories for all of the distributions (call them slaves). So, consider: /master/slave1 /master/slave2 ... /master/slaven then i rdist this to all of my slaves. In the /master directory all of the standard cassandra distribution. In the /master/slave* directory all of the machine dependent stuff. Also in /master I have a .profile with: -bash-4.1$ cat /master/.profile # export CASSANDRA_HOME=$HOME/run SHOST=`hostname | sed s'/\..*//'` export CASSANDRA_CONF=$CASSANDRA_HOME/conf/$SHOST export CASSANDRA_INCLUDE=$CASSANDRA_HOME/conf/$SHOST/cassandra.in.sh . $CASSANDRA_HOME/conf/cassandra-env.sh PATH=$HOME/run/bin:$PATH echo 'to start cassandra type cassandra' this leaves me with this environment on each slave (slave1 example): -bash-4.1$ env | grep CAS CASSANDRA_HOME=/usr/share/cassandra/run CASSANDRA_CONF=/usr/share/cassandra/run/conf/slave1 CASSANDRA_INCLUDE=/usr/share/cassandra/run/conf/slave1/cassandra.in.sh Using this technique I maintain my Cassandra cluster on 1 machine and rdist to the participants.Rdist makes each node independent. -greg On Sun, Jun 24, 2012 at 1:11 PM, aaron morton aa...@thelastpickle.com wrote: Idea is to avoid having the copies of cassandra code in each node, If you run cassandra from the NAS you are adding a single point of failure into the system.
