Hi everyone,
I'm using HiveContext and SparkSQL to query a Hive table and doing join
operation on it.
After changing the default serializer to Kryo with
spark.kryo.registrationRequired = true, the Spark application failed with
the following error:
java.lang.IllegalArgumentException: Class is not registered:
org.apache.spark.sql.catalyst.expressions.GenericRow
Note: To register this class use:
kryo.register(org.apache.spark.sql.catalyst.expressions.GenericRow.class);

I'm using Spark 1.3.1 (HDP 2.3.0) and submitting Spark application to Yarn
in cluster mode.
Any help is appreciated.
