Not Able to Run Cassandra on AWS Ubuntu Instance

Question

I'm having openJDK 1.7 version and Have installed Cassandra 2.1.8. I have changed the CLASSPATH of CASSANDRA_HOME as well but I'm getting following error.

> root@ip-172-31-57-69:/usr/local/apache-cassandra/bin# export CASSANDRA_HOME=/usr/local/apache-cassandra/
root@ip-172-31-57-69:/usr/local/apache-cassandra/bin#  echo $CASSANDRA_HOME;
/usr/local/apache-cassandra/
root@ip-172-31-57-69:/usr/local/apache-cassandra/bin# cd /usr/local/apache-cassandra/
root@ip-172-31-57-69:/usr/local/apache-cassandra# bin/cassandra
