Bug fixes
- BUGFIX: Installation of an Apache Spark release is no longer needed for more recent Cloudera Hadoop releases in order for Spark jobs to work (and not give an Unknown/unsupported param error). Use the new Spark 1.6 (CDH) Spark version connection setting in this case.
- BUGFIX: K-Means model apply inside Radoop Nest no longer fails with ClassNotFoundException or NoClassDefFoundError
- BUGFIX: Fixed Cannot initialize Cluster error when a certain failover proxy provider class is used on the cluster (org.apache.hadoop.yarn.client.RequestHedgingRMFailoverProxyProvider) and the connection is imported
- BUGFIX: Spark Script with R no longer relies on the private RDD API in Spark 2.x
- BUGFIX: Quick fix that adds a Type Conversion operator now selects the proper target type
