We are trying to use the Teradata conector for hadoop. We are launching the job from a client hots( lets call it edge node ) where there is just a Hadoop client and it sends the job to a Hadoop cluster in the backend. This node is in the frontend, which should not have connection to the Teradata.
BUT when we try to use Teradata connector for hadoop, the edge node tries to connect directly to the Teradata. We were supposing that the nodes of the hadoop cluster were the only ones who should have connectivity with the Teradata, but our surprise is that the client in the edge node tries to do a connection directly to the Teradata before startint the MR jobs.
Please we need help about this, connectivity seems different from what the documents say.
