Thanks guys for joining the discussion, I hope you don't mind if I continue to argue a bit more. The core intelligence and functionality of Cassandra server lays in the Java classes, which reside in jar archives. This is the place where the main functionality updates take place. To ease the

Re: Three scripts needed to run the server, Why?

Also, you can use bash to debug bin/cassandra: PS4=' $BASH_SOURCE:$LINENO: ' bash -x bin/cassandra This should print the filename of the file being executed/sourced and the line number being currently executed, so it should be easier to find out what happened, where and when. Of course,

Three scripts needed to run the server, Why?

Greetings, I've been working with Cassandra for more than a year but I still wonder about one thing: To run the server there is a bash script (cassandra) which uses another script (cassandra.in.sh) which uses yet another bash script (cassandra-env.sh). What is the reason behind this? Why there
