I'm trying to filter on a small part of a huge C* table by using: val snapshotsFiltered = sc.parallelize(startDate to endDate).map(TableKey(_)).joinWithCassandraTable("listener","snapshots_tspark") println("Done Join") //******* //get only the snapshots and create rdd temp table val jsons = snapshotsFiltered.map(_._2.getString("snapshot")) val jsonSchemaRDD = sqlContext.jsonRDD(jsons) jsonSchemaRDD.registerTempTable("snapshots_json") With: case class TableKey(created: Long) //(created, imei, when)--> created = partititon key | imei, when = clustering key And the cassandra table schema is:

I am trying to run the following query SELECT edge_id, b_id FROM booking_by_edge WHERE edge_id IN ? I bind Java list of Long's as a parameter and I get an exception SyntaxError: line 0:-1 mismatched input '<EOF>' expecting ')' (ResultSetFuture.java:242) If I try to use (?) it expects single Long item to be bound, but I need a collection Is there an error in my syntax? Tested in Cassandra 2.1.3, the following code snippet works: PreparedStatement prepared = session.prepare("SELECT edge_id, b_id FROM booking_by_edge WHERE edge_id IN ?;"); List<Long> edgeIds = Arrays.asList(1L, 2L, 3L); session

The example above returns 10 rows starting from row 20. How can I achieve the same effect in CQL? I have found some solutions on Google, but all of

I am trying to use Spark Cassandra Connector in Spark 1.1.0. I have successfully built the jar file from the master branch on GitHub and have gotten the included demos to work. However, when I try to load the jar files into the spark-shell I can't import any of the classes from the com.datastax.spark.connector package. I have tried using the --jars option on spark-shell and adding the directory with the jar file to Java's CLASSPATH. Neither of these options work. In fact, when I use the --jars option, the logging output shows that the Datastax jar is getting loaded, but I still cannot import
