CDH: is HDFS Gateway role mandatory?

Hello,

The installation manual of StreamSets on CDH states:

To write to HDFS, colocate Data Collector on a node with the HDFS Gateway role

I don't have any HDFS Gateway role enabled on the CDH cluster, and StreamSets seems to be able to write to HDFS (some preliminary testing works) without this condition. Do you identify any problem if I skip this requirement?

Thank you, Gerasimos
