Datastax Cassandra without root

Question

I am trying to install and run the Datastax cassandra community edition on Redhat Linux but I don't have root privileges. I extracted the tar in my home directory but I'm unable to do ./cassandra

I am doing this on a HPC cluster and thought I'd install Cassandra in my home directory and save the data in a scratch space we've been provided (home directory doesn't have enough space to hold entire data)

I would appreciate any help! Thanks!

From the installation docs for DataStax community edition, the only other step you need is to create the data and log directories:

$ sudo mkdir /var/lib/cassandra
$ sudo mkdir /var/log/cassandra
$ sudo chown -R  $USER: $GROUP /var/lib/cassandra
$ sudo chown -R  $USER: $GROUP /var/log/cassandra

If you are using a different location, that's fine. Just make sure to create the dirs and assign owners (like above) and also set the appropriate values in cassandra.yaml (data_file_directories, commitlog_directories, saved_caches_directory) and log4j-server.properties.

A more detailed log of the results you're seeing would confirm whether this is the problem.
