Followed the instructions here: http://www.datastax.com/documentation/cassandra/2.0/cassandra/install/installAMILaunch.html
Installed OpsCenter on m3.large. When launching an instance, I get this error:
Error: Start stage failed: Failed to start node [ip]: Timed out waiting for Cassandra to start.
The log on the individual server is:
CassandraDaemon.java (line 235) Directory /mnt/cassandra/data doesn't exist CassandraDaemon.java (line 239) Has no permission to create /mnt/cassandra/data directory
What do I need to do to let it have the permission? I use a key/secret pair that have all rights on AWS to generate more nodes.
