Hello Uttam
Thanks for your useful article.
Can you just explain me "In a multi-node CAS environment when the Data Connector is installed on all Nodes"?
We deploy several cas servers in our environement :

[sas_casserver_worker]
CASWorker1
CASWorker2
CASWorker3
CASWorker4

We also deployed Impala odbc client on all servers, we configure odbc.ini on all servers and also modify our cas_usermods.settings on all server.
But we still obtain in the log :

NOTE: Performing serial LoadTable action using SAS Data Connector to Impala.
WARNING: The value of numReadNodes(9) exceeds the number of available worker nodes(1). The load will proceed with numReadNodes=1.

Maybe we miss something but we cant' find what.

Regards
Fabrice
