Hi Todd,

We are using Apache C* 2.1.3, not DSE. We got Tableau to work directly with C* 
using the ODBC driver, but now would like to add Spark SQL to the mix. I 
haven’t been able to find any documentation for how to make this combination 
work.

We are using the Spark-Cassandra-Connector in our applications, but haven’t 
been able to figure out how to get the Spark SQL Thrift Server to use it and 
connect to C*. That is the missing piece. Once we solve that piece of the 
puzzle then Tableau should be able to see the tables in C*.

Hi Pawan,
Tableau + C* is pretty straight forward, especially if you are using DSE. 
Create a new DSN in Tableau using the ODBC driver that comes with DSE. Once you 
connect, Tableau allows to use C* keyspace as schema and column families as 
tables.

Hi Todd,

Thanks for the link. I would be interested in this solution. I am using DSE for 
cassandra. Would you provide me with info on connecting with DSE either through 
Tableau or zeppelin. The goal here is query cassandra through spark sql so that 
I could perform joins and groupby on my queries. Are you able to perform spark 
sql queries with tableau?

Thanks,
Pawan Venugopal

with the standard Apache Cassandra version.

FWIW, 
http://www.datastax.com/dev/blog/datastax-odbc-cql-connector-apache-cassandra-datastax-enterprise,
 provides an ODBC driver tor accessing C* from Tableau.  Granted it does not 
provide all the goodness of Spark.  Are you attempting to leverage the 
spark-cassandra-connector for this?

Hi –

Is anybody using Tableau to analyze data in Cassandra through the Spark SQL 
Thrift Server?

Thanks!
