Syntax

Required Arguments

Example

Syntax

SPDSHPRD=NO | YES

Required Arguments

NO

specifies that parallel processing occurs only if a Read operation includes WHERE processing. This is the default behavior.

YES

requests parallel processing for all Read operations.

Example

%let spdshprd=yes;

Note: Because SPD Server must be enabled to operate in select Hadoop environments, you might want to determine whether a libref is in a Hadoop domain. For example, to determine whether the libref My_Lib is in a Hadoop domain, submit the LIBNAME LIST statement libname my_lib list;. If the queried libref is in a Hadoop domain, SPD Server returns HADOOP=YES.
