The SAS Data in HDFS 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 upper, mixed, or lower case. 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.
