The SASHDAT engine
can be used to read CSV files. The engine does not write CSV files.
Specify this option to use the file as input for a SAS High-Performance
Analytics procedure or the SAS LASR Analytic Server.
The filename for CSV files in HDFS can be uppercase, mixed case, or lowercase. If
more than one file in the directory
has the same name (but with different casing), the engine does not read the file because
the file reference is ambiguous.
