If you have a Cassandra cluster i am sure you have the problem of viewing the data instantly. Cassandra CLI is one of the tools but it would be easier if it has a nice UI and would more convenient for administrators. Cassandra Explore has been developed to make the things easier for Cassandra users.
Download the Cassandra Feature pre installed WSO2 Carbon Server.  . (Until we officially release Cassandra Explorer with Cassandra feature lets use this.)
Extract the downloaded product and lets refer extracted folder as CARBON_HOME.
You have two different options with Cassandra feature.
