Modifying cassandra.yaml has no effect?
Hi,
I change the `data_file_directories` field from /var/lib/cassandra to
/mnt/cassandra in conf/cassandra.yaml, stop and restart cassandra but
it doesn't seem to affect Cassandra at all. Does cassandra deployed by
whirr use cassandra.yaml at all? Thanks.

every whirr service has a 'intsall_<service_name>.sh' and
'configure_<service_name>.sh', which has all the bash commands for setting
up the servers that whirr starts.
You can override these scripts and add your own custom functionality. To do
this, create a directory called "functions" in the whirr folder. Then copy
the file
"whirr-0.6.0-incubating/services/cassandra/src/main/resources/functions/configure_cassandra.sh"
into the "functions" folder, and modify the file to update the yaml file the
way you want.
Hope that helps...
John

Thank you. This is very useful. I didn't know there is a
"configure_cassandra.sh" script.

we did the same thing, but overrode the configure_cassandra.sh script in the
functions folder, and did sed commands to to update all the output folders
to point to /mnt as their root. This way you dont have to log on to each
cassandra machine in the ring, stop it, reconfig it, and restart it. easy
peazy!

Oh. Thanks. I was editing /use/local/apache-cassandra/conf/cassandra.yaml

Cassandra config files should be in /etc/cassandra/conf
Are you editing /etc/cassandra/conf/cassandra.yaml?
