ccm does not start about ccm HOT 11 CLOSED

Same as #64: #64

This issue occurs if the JVM fails before even starting Cassandra.

My fork has a temporary fix:
https://github.com/Flux7Labs/ccm

Please try and let me know if works for you.

Just installed ccm but unfortunately it does not start. Tried different
versions of Cassandra (0.8.6, 1.2.5), different java versions (latest JDK6
and JDK7) but can't get it going. Used "ccm start -v" and "ccm start -v
--no-wait" but ccm just hangs and produces no output. Pid file is generated
for first node but the process itself does not exist (anymore). Also tried
to use "python2 -m trace --trace /usr/bin/ccm start" but don't get any
reasonable output.

As I am by far no Python expert, is there a good way to troubleshoot the
issue?

Hi Aater,

thanks a lot for your patch. At least I'm getting error messages now!

For Cassandra 0.8.6 it says: Error: Could not create the Java Virtual Machine.
I am using latest JDK 7.

For Cassandra 1.2.5 it says: Error: Could not find or load main class org.apache.cassandra.service.CassandraDaemon

Both for standard user and root. You've got any idea what the problem could be? Of course I'm mainly interested in Cassandra 1.2.5 because of its feature set. Tried 0.8.6 just because it was used in the ccm docs and assumed it has been tested and worked with others.

You must use JAVA6 and that the Oracle JDK v 1.6, not the Open JDK.

Which OS are you on? If its Ubuntu, you can follow my training script:

https://github.com/Flux7Labs/cassandra-training/blob/master/utils/ubuntu_setup.sh

... to setup JAVA.

Let me know if this doesn't solve the issue.

There are some advanced ccm techniques I have learned but we will get into
it only if the simpler ones fail.

Hi Aater,

am using Archlinux. Set up a box with latest JDK6 - but same issue. (Archlinux installs the jdk in /opt/java.) Tried several Cassandra environment variables and adapted cassandra.in.sh. But could not resolve the issue.

I think I leave it this way. Already spent too much time fixing the problem. Will use some virtual boxes instead to setup a Cassandra cluster.

But anyway, thanks a lot for your help, Aater. Highly appreciated!

I seem to be experiencing this issue as well.

Error: Could not find or load main class org.apache.cassandra.service.CassandraDaemon

@maater Why do you have to use JDK6 for 1.2.x ? JDK7 is supported. Additionally JDK7 is required for Cassandra >= 2.0

I saw this if I did a create the first time without ant installed (so the compile failed). Since it pulled all future clusters from the ~/.ccm/repository it would always give this error when starting a cluster from that version. I was able to resolve by just deleting the repository for that version

rm -Rf ~/.ccm/repository/1.2.13

and re-created the cluster

Manually removing the (half-baked) repository, as @clohfink suggests, fixes it.

This appears to be two separate issues, a duplicate of #64, and running without ant installed, which has since been added to the list of requirements.

Thanks clohfink! fixes my issue.

Many thanks @clohfink - this was exactly my issue, your suggestion fixed it.

Many thanks @clohfink for me too
