Thanks for the response !!
The document says , " If you have installed and activated the SAS Embedded Process on a Hadoop cluster, it is possible for DATA step code to be executed in parallel against the input data residing on the HDFS file system. "
Does it mean , It allows the normal Base SAS codes to run with SAS EP ? I was confirmed from SAS that EP is widely for DS2 performance enhancements , we may have to convert the codes to DS2 in order to leverage the performance .
