I have novice to cassandra and tried my hands to install cassandra-2.1.2 on centos 7.0. After complete installation execute cqlsh command and created few keyspace(s) and column family. Which seems to me in first glance its working perfectly.
But later onwards i realized below issues: 1> when i execute "service cassandra status" command, i got below error: Output:Cassandra dead but pid file exists. I googled the above issue and found some links http://www.datastax.com/support-forums/topic/dse-dead-but-pid-file-exists https://baioradba.wordpress.com/2014/06/13/how-to-install-cassandra-on-centos-6-5/ and found that I had same configuration mentioned in above links but the same error still persists. Please tell me the root cause and how to resolve it. 2> Second issue is in the cassandra.log file. When I analysed the cassandra.log file there was an expection as : Expecting URI in variable: [cassandra.config]. Please prefix the file with file:/// for local files or file://<server>/ for remote files. Aborting. Below is the complete log: 12:01:40.816 [main] ERROR o.a.c.config.DatabaseDescriptor - Fatal configuration error org.apache.cassandra.exceptions.ConfigurationException: Expecting URI in variable: [cassandra.config].

I again searched the same issue in google and but the links were not that useful as they contained the java class code for cassandra.config . Again please tell the root cause and how to resolve it? Thanks in advance. -- Thanks, Mohit Garg
