I have a Cassandra cluster of two nodes. I am using Cassandra 3.10.
when I tried to run nodetool status, by default it is calling /usr/bin/nodetool and gives result You must set the CASSANDRA_CONF and CLASSPATH vars. 
CASSANDRA_HOME and CASSANDRA_HOME/bin is already set in bashrc.
When I run CASSANDRA_HOME/bin/nodetool status It is showing correct result, both the nodes are up.
My problem is how can I make CASSANDRA_HOME/bin/nodetool as default. So that I can call it from any where.
PS: cqlsh is also showing same behavior.
Thanks.
