So I would like to allow an additional user account to be able to run Cassandra commands, such as nodetool status, etc. This account is not the account under which Cassandra runs.
I have a four node cluster, and the installation was done via tarball. I have the path set and everything looks to be in order. For three of the nodes everything works fine, but on the fourth node everytime I try to run nodetool I get the following error: Cannot determine CASSANDRA_BIN.
No matter what I try on this node, I get the same problem. To verify the issue isn't this specific account I've tried creating a new user, adding it to the necessary group (so permissions aren't an issue) and giving it the correct path, and yet again I keep getting the Cannot determine CASSANDRA_BIN.
The user under which Cassandra runs is fine on this node, I'm just wondering what could be causing this issue. It seems that everything is identical to the other 3 nodes, however I guess something has to be different here (I did not build this cluster so I don't know if something weird was done with this node that wasn't with the others).
The script that generates that error attempts to determine the location of CASSANDRA_BIN by looking for the cassandra script in one of $CASSANDRA_HOME/bin, /usr/bin or /usr/sbin.
So for this to fail the user attempting to launch nodetool either doesn't have read permissions to one or all of those locations or the cassandra script doesn't exist at any of those locations.
