In order to install Cassandra, I've done the following: 1. Downloaded the TAR file. 2. Extracted the file. 3. Set the path for data and commitlog directories in the yaml file.
Now when I run Cassandra, I'm getting the following error: "Java HotSpot (TM) 64-Bit Server VM warning: Cannot open file. /..logs/gc.log due to No such file or directory"
What's causing this problem? Do I need to do something else before running it.
OS: RHEL 6.5 Cassandra version: 3.11.1

Cassandra logs are stored in the /<inst_root>/apigee/var/log/cassandra directory on each node. By default, a maximum of 50 log files, each with a maximum size of 20 MB, can be created; once this limit is reached older logs are deleted when newer logs are created.
These logs by default live in ${CASSANDRA_HOME}/logs , but most Linux distributions relocate logs to /var/log/cassandra . Operators can tune this location as well as what levels are logged using the provided logback. xml file.
Cassandra logs all gcs in a log file called gc.log. The path of this file is defined in cassandra-env.sh:
#GC log path has to be defined here because it needs to access CASSANDRA_HOME
JVM_OPTS="$JVM_OPTS -Xloggc:${CASSANDRA_HOME}/logs/gc.log"
Make sure you have a folder in your cassandra folder called logs and that whatever user you're running cassandra with has write permisssions to this folder.
