How to see Cassandra List / Set / Map values from Spark Hive Thrift JDBC?
Hi all,
I have asked this question here on StackOverflow:
http://stackoverflow.com/questions/35222365/spark-sql-hivethriftserver2-get-liststring-from-cassandra-in-squirrelsql
But hoping I get more luck from this group. When I write a Java SparkSQL
application to query a CassandraSQLContext, and print out a List column, it
prints out the values eg:
WrappedArray(mj485, pd153, ws019)
But when I query this same column from SquirrelSQL connecting to the Spark
HiveThriftServer2 JDBC, I get:
<UnknownType (2,003)>
Does anyone have any suggestions as to how I can get HiveThriftServer to
return the values, similar to how Java code does it?
Many thanks,
Matthew
PS I am running Spark 1.5.1, Cassandra 2.1.10
