Rules and Guidelines for Processing Hierarchical Data on the Spark Engine

There are processing differences when you work with complex data types in a mapping that runs on the Spark engine.

Consider the following rules and guidelines when you use complex data types in a mapping that runs on the Spark engine:

You cannot read hierarchical data from or write hierarchical data to a Hive source in a dynamic mapping.

When you read hierarchical data from a Hive source, you cannot enable Hive LLAP for Hive queries.

When you read hierarchical data from a Hive source, the Spark engine converts float type data to double. Use the double data type when you read from and write to a Hive source to prevent precision errors.

When you write date/time data within a complex data type to a Hive target using HDP 3.1, configure the timezone as UTC. In the Hadoop connection Spark advanced properties, append “-Duser.timezone=UTC” to the end of the value for the following properties:

spark.driver.extraJavaOptions

spark.executor.extraJavaOptions
