Unable to copy data from hdfs to vertica using hdfs connector(kerberos secured)

Hi Vertica community,

If I execute the same query from vsql shell it qorks just fine(I'm printing the COPY query being used at the console for debuggin). Also, I am able to curl the same WebHDFS url from vertica hosts successfully.

Any help in this regard would be really helpful. Many thanks!
