This code uses SAS SQL to access a Hadoop table.
proc sql;
create table work.a as select * from hdp.newtab;
quit;
SAS data is then loaded into Hadoop.
data hdp.newtab2;
set work.a;
run;
Use implicit pass-through SQL to extract only 10 rows from the newtab table and load
the work SAS data set with the results.
proc sql;
connect to hadoop (server=hxpduped);
create table work.a as
select * from connection to hadoop (select * from newtab limit 10);
