Subject RE: Accessing Cassandra Data from Excel / Tableau / R
Date Wed, 18 Feb 2015 02:07:18 GMT
Thanks, Peter. 
Any pointers on getting that working? Also, don't think Tableau supports JDBC (it does support
ODBC). I've been able to start beeline (i.e. thriftserver) and connect Tableau to it via the
Simba ODBC connector for Spark. But no idea how to let "it" (hive or spark) know where Cassandra
is and how to access it.
Any help is appreciated.

Hive can connect to Cassandra, so that means you can point Tableau to hive using JDBC.

As long as you map Hive to cassandra, you should be able to query data just like regular hive

What's a good way to load some cassandra data (perhaps result of a cql query) into Excel /
Tableau? I see DSE has support, but that's not always an option. Simba do an odbc connectory
that currently doesn't support UDTs + collections properly (and it's expensive). Is there
a way to use Spark to provide a gateway to Cassandra data to the traditional BI tools? Perhaps
with the ThriftServer? RCassandra also seems stuck in the distant there any new
news on that front?
The reason I ask is some non-programmers simply want to look at some data by themselves, with
some cql. I'd like to be able to give them that without data exports.
