How to read data from local cassandra cluster
Hi,
I have install Cassandra locally (DataStax Enterprise to be specific).
Everything seems to work ok. For example, I can upload a test file into CFS
or open a Spark REPL.
However, when it comes to my very own Spark application, I can't understand
how to modify sc.textFile("/user/testuser/words.txt") so that I can read
the file I just uploaded to my local DataStax installation.
How should I refer to the associated host?

Not a Cassandra question so this isn't the right list, but you can just upload the file to CFS and then access it by the path "cfs://filename".
However, since you have DSE you may want to contact support for help with pathing in DSE using CFS and Spark.
