Hi Vishanth, Can you please copy Cassandra into some directory under your $HOME directory and execute *./cassandra* command after moving to the *$CASSANDRA_HOME/bin* directory. Also make sure to switch your JVM to some jdk 1.7 version prior to run the above command since Cassandra needs jdk 1.7or later version. As Niranda mentioned this could be a permission issue. Setting the $CASSANDRA_HOME environment variable is also optional.
