MapR Stream Producer Error, could not get TopicInfo, err 13

Hello StreamSet's experts. I am trying to configure a Mapr Stream Producer. The goal is to take the contents of a file and dump it into a stream. But when I preview it I get this error:

"Error getting metadata for topic '/scada/vendor1:scada_vendor1' from MapR Streams. Reason: org.apache.kafka.common.errors.UnknownTopicOrPartitionException: could not get TopicInfo, err 13"

I have a 3 node MapR cluster that is SEPERATE from the StreamSets server. They can all talk to each other. I don't see anywhere to specify my MapR Streams REST hostnames or ports. I ran the mapr setup for the streamsets binary directoy with no errors listed here: https://streamsets.com/documentation/datacollector/latest/help/index.html#Installation/MapR-Prerequisites.html#concept_jgs_qpg_2v

Also the stream and topic have been created on the MapR cluster:

ubuntu@ip-172-16-1-30:/mapr/csmykay-us-east-1.cluster.com/scada$ ll vendor1 lr-------- 1 mapr mapr 2 Sep 11 04:10 vendor1 -> mapr::table::2113.50.262370

mapr@ip-172-16-1-30:~$ maprcli stream topic list -path /scada/vendor1 partitions maxlag logicalsize topic consumers physicalsize 1 0 0 scada_vendor1 0 0

This is the full error:

"Error getting metadata for topic '/scada/vendor1:scada_vendor1' from MapR Streams. Reason: org.apache.kafka.common.errors.UnknownTopicOrPartitionException: could not get TopicInfo, err 13: conf.topic"

I feel like this external StreamSets SDC server does not know how to communicate with MapR Streams but can't find any additional topics on how to configure it.
