Pentaho Spoon Cassandra Connection Error

While doing ETL process using spoon I got the error like this.

    An unexpected error occurred in Spoon:  
    Could not initialize class org.apache.thrift.transport.TSocket

After surfing net for the solution I finally found the solution on stackoverflow. And here is the solution provided by them.

Just copy the jar files mentioned below

        data-integration/lib/log4j-1.2.16.jar
        data-integration/plugins/pentaho-big-data-plugin/lib/slf4j-api-1.7.3.jar
        data-integration/plugins/pentaho-big-data-plugin/lib/slf4j-log4j12-1.7.3.jar

to

        data-integration/plugins/pentaho-cassandra-plugin/lib/

P.S. - Thanks to the community of stackoverflow.
