Hi @MALIGHT,
READ_METHOD=jdbc bypasses HDFS processing. This is an indication that you are missing some JARs.
You may want to try setting SAS_HADOOP_RESTFUL=1 environment variable. I think this option first appeared in SAS 9.4M3, but I could be wrong. This option enables HDFS processing to use the REST interface. This limits the need for certain JARs, too. If you set it and don't see a change in behavior it is probably because it wasn't implemented at M2.
I think your best bet is to go through the process of getting the correct set of JARs.
