title: gc.log file error when running cassandra
body: <p>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. </p>
  
  <p>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"</p>
  
  <p>What's causing this problem? Do I need to do something else before running it.  </p>
  
  <p>OS: RHEL 6.5
  Cassandra version: 3.11.1</p>
