r - Unable to Connect to Cassandra Database from R using JDBC

Question

I am trying to connect R with Cassandra. Following is my code:

library(RJDBC)
#Load in the Cassandra-JDBC diver
cassdrv <- JDBC("org.apache.cassandra.cql.jdbc.CassandraDriver",
         list.files("D:/cassandra/lib",pattern="jar$",full.names=T))

#Connect to Cassandra node and Keyspace
casscon <- dbConnect(cassdrv, "jdbc:cassandra://192.168.1.20:9042/demodb")

When I run above code in R, I get following error:

Error in .jcall(drv@jdrv, "Ljava/sql/Connection;", "connect", as.character(url)[1], :
java.sql.SQLNonTransientConnectionException: org.apache.thrift.transport.TTransportException: Read a negative frame size (--2080374784)!

Any ideas how to solve this error? Thanks in advance!
