latest versions of Priam use default properties defined in this file

you can override all of them in SDB. I had the problem with priam.cass.startscript which points to /mnt/cassandra.
Also check tomcat process permissions, it is supposed to modify cassandra.yaml file. Seed list may be one more issue, they use public IP instead of names, so they are not accessible unless you open port 7000 to everyone. Honestly, it was quite painful to use Priam 1.2

Thank you,

This is more of a Priam question, but asking it in the Cassandra forum since many of you may be using Priam to backup data from Cassandra.

We are planning to migrate to Cassandra 1.2.5 in production. Which is the most stable version of Priam which is compatible with Cassandra 1.2.5 and is production-ready?

I am currently testing Priam version 1.2 (from the git branch - with cassandra 1.2.5. I followed all the setup instructions from the Priam wiki. I have changed my default property priam.cass.home to point to my cassandra installation located at /usr/local/cassandra.

When I launch my auto scale group and log-in to the node, I see that cassandra is not up. In the catalina.out, I see a line "Couldnt execute the task because of /mnt/cassandra/conf/cassandra.yaml (No such file or directory)". I believe that this is because the default cassandra home is /mnt/cassandra in Priam version 1.2. But I have changed the priam.cass.home attribute value in PriamProperties domain in SDB. Reading all the attribute values for the items in PriamProperties domain in sdb returns correct values. Is there something else that I need to change for Priam to locate the correct cassandra home directory?

Further in the catalina.out log, I see the error - "Exception --> Status Code: 403, AWS Service: Amazon S3, AWS Request ID: ....., AWS Error Code: AccessDenied, AWS Error Message: Access Denied".
What other permissions do I need to set on my AWS instance for Priam to startup with Cassandra?

Also, does anyone have a good architecture diagram of Priam with Cassandra. It would be really useful to get a sense of how the system works. Could not find it anywhere.

Thanks in advance for your help!
