@EFasdfSDfaSDFG  Took sometime to do a feasibility study and found a couple of things from our Internal resources. 1. FYI: The native Ozone REST API is completely superseded by the S3 REST API.

If not, Please follow my update: ----------------------------------------- Since this request is made on the legacy Cloudera Lineup - CDH6.x, Before we go about the architectural advisory I regret to inform you that CDH6.x is announced to be EoS(End-Of-Support) in March 2022.
