Hello,
I'm trying to read data from a table stored in cassandra with pyspark.
I found the scala code to loop through the table :
"cassandra_rdd.toArray.foreach(println)"
How can this be translated into PySpark ?
code snipplet :
sc_cass = CassandraSparkContext(conf=conf)
cassandra_rdd = sc_cass.
Hello,
I'm writing an application in Scala to connect to Cassandra to read the
data.
My setup is Intellij with maven. When I try to compile the application I
get the following *error: object datastax is not a member of package com*
*error: value cassandraTable is not a member of
org.apache.spark.S
its fixed now, adding dependecies in pom.xml fixed it
com.datastax.spark

Hello,
Trying to write data from Spark to Cassandra.
Reading data from Cassandra is ok, but writing seems to give a strange
error.
Exception in thread "main" scala.ScalaReflectionException: is not a

use the spark-shell command and the shell will open
type :paste abd then paste your code, after control-d
open spark-shell:
