Hi,
I'm not sure what's the problem with the virtual lab.
The hue GUI is not working, attached is the error screen shot.
Also when,I executed the below proc hadoop code:
%let std=&SYSUSERID; %let stdpw=Metadata0;
proc hadoop username="&std" verbose;
hdfs mkdir="/user/&std/DIACHD/data";
run;
Got the below error:
ERROR: java.net.ConnectException: Call From server1.demo.sas.com/10.250.86.140 to server2.demo.sas.com:8020 failed on connection
exception: java.net.ConnectException: Connection refused; For more details see:
