My suggestion is to use Java or Scala instead of Python. For Java/Scala both the Datastax and Stratio drivers are valid and similar options. As far as I know they both take care about data locality and are not based on the Hadoop interface. The advantage of Stratio Deep is that allows you to integrate Spark not only with Cassandra but with MongoDB, Elasticsearch, Aerospike and others as well. Stratio has a forked Cassandra for including some additional features such as Lucene based secondary indexes. So Stratio driver works fine with the Apache Cassandra and also with their fork.
You can find some examples of using Deep here: https://github.com/Stratio/deep-examples Please if you need some help with Stratio Deep do not hesitate to contact us. 2015-02-11 17:18 GMT+01:00 shahab <shahab.mok...@gmail.com>: > I am using Calliope cassandra-spark connector( > http://tuplejump.github.io/calliope/), which is quite handy and easy to > use! > The only problem is that it is a bit outdates , works with Spark 1.1.0, > hopefully new version comes soon. > > best, > /Shahab > > On Wed, Feb 11, 2015 at 2:51 PM, Marcelo Valle (BLOOMBERG/ LONDON) < > mvallemil...@bloomberg.net> wrote: > >> I just finished a scala course, nice exercise to check what I learned :D >> >> Thanks for the answer! >> >> From: user@cassandra.apache.org >> Subject: Re: best supported spark connector for Cassandra >> >> Start looking at the Spark/Cassandra connector here (in Scala): >> https://github.com/datastax/spark-cassandra-connector/tree/master/spark-cassandra-connector/src/main/scala/com/datastax/spark/connector >> >> Data locality is provided by this method: >> https://github.com/datastax/spark-cassandra-connector/blob/master/spark-cassandra-connector/src/main/scala/com/datastax/spark/connector/rdd/CassandraRDD.scala#L329-L336 >> >> Start digging from this all the way down the code. >> >> As for Stratio Deep, I can't tell how the did the integration with Spark. >> Take some time to dig down their code to understand the logic. >> >> >> >> On Wed, Feb 11, 2015 at 2:25 PM, Marcelo Valle (BLOOMBERG/ LONDON) < >> mvallemil...@bloomberg.net> wrote: >> >>> Taking the opportunity Spark was being discussed in another thread, I >>> decided to start a new one as I have interest in using Spark + Cassandra in >>> the feature. >>> >>> About 3 years ago, Spark was not an existing option and we tried to use >>> hadoop to process Cassandra data.
