ORAAH Based Functions for Spark/ORE

Following framework functions will help in connecting/disconnecting Spark/ORE(Hive). Internally these functions will use ORAAH for Spark/ORE connections. These functions will return TRUE on success and FALSE in case of any failures with the proper error message in the logger.

ofs_ORAAH_spark_connect()

ofs_ORAAH_spark_disconnect()

ofs_ORAAH_hive_connect()

ofs_ORAAH_hive_disconnect()

All the four functions return -

TRUE : on Success

FALSE : on Failure

Note:

ofs_ORAAH_spark_connect/ofs_ORAAH_spark_disconnect should be
                                        called first/last, before using any ORCH-Spark related
                                        function, like
                                        orch.glm2()

.ofs_ORAAH_hive_connect/ofs_ORAAH_hive_disconnect
                                        should called first/last, before using any ORCH-ORE related
                                        functions.
