Create Big Data Test Environment

Creates a fully functional big data environment for testing purposes, including Apache Hive, Apache Spark and a remote file system. This node has no own configuration, instead it will read its configuration from a file called flowvariables.csv from the root of the KNIME workspace. This file is expected two provide keys and values. These can be used to control what this node does.

Note: This node only creates a new Spark context upon its first execution after KNIME has started, or after the context has been destroyed. The Spark context created by during its first execution is meant to be shared between KNIME testflows.

Note: This node uses the old connection information based file system output port.
