Hello! I'm working on a POC with Spark SQL, where I’m trying to get data from Cassandra into Tableau using Spark SQL.
Here is the stack: - cassandra (v2.1) - spark SQL (pre build v1.1 hadoop v2.4) - cassandra / spark sql connector (https://github.com/datastax/spark-cassandra-connector) - hive - mysql - hive / mysql connector - hive / cassandra handler (https://github.com/tuplejump/cash/tree/master/cassandra-handler) - tableau - tableau / spark sql connector I get an exception in spark-sql (bin/spark-sql) when trying to query the cassandra table (java.lang.InstantiationError: org.apache.hadoop.mapreduce.JobContext), it looks like a missing hadoop dependency; showing tables or describing them work fine. Do you know how to solve this without of hadoop? Is Hive a dependency in Spark SQL?
