Requirements for DATA Step Processing

In order to run a DATA step program in Hadoop, the following is required:

The DSACCEL= system option is set to ANY.

For more information about the DSACCEL= system option, see SAS System Options: Reference.
The code must contain a LIBNAME statement using the SAS/ACCESS HADOOP engine.

For more information about the Hadoop LIBNAME statement, see SAS/ACCESS for Relational Databases: Reference.
The input and output files must use the same libref for the HADOOP engine.
The DATA statement must be followed immediately by the SET statement.
This example demonstrates these requirements:
```
options dsaccel=any;

libname hdone hadoop;
data hdone.out;
set hdone.in;
/* DATA step code */
run;
```
The SAS Embedded Process must be running on the cluster where the input and output files exist.
