Subject Re: cassandra + spark / pyspark

   DataStax , Startio are required mesos, hadoop yarn other third party to
get spark cluster HA.

What in case of calliope?
Is it sufficient to have cassandra + calliope + spark to be able process
In my case we have quite a lot of data so doing aggregation only in memory
- impossible.

Does calliope support not in memory mode for spark?
