The SAS Data in HDFS engine replaces the functionality provided by the OLIPHANT procedure. For more information, see Using the SAS Data in HDFS Engine.

The OLIPHANT procedure is used to add, delete, and manage SASHDAT files that are stored in the Hadoop Distributed File System (HDFS). The procedure is used to add data sets from SAS libraries into HDFS. Once the data is in HDFS, it is stored as a SASHDAT file. The filename for the SASHDAT file is always lowercase. The procedure is also used to remove SASHDAT files from HDFS. For the data in SASHDAT files, the procedure can provide information about the data such as file size, block size, column count, row count, and so on.

The SAS LASR Analytic Server reads data in parallel from the SASHDAT files that are added to HDFS.
