stream upstream add

Registers a stream as an upstream source for a given stream. For example, if you wanted to replicate messages from Stream_A to Stream_B, Stream_A would be the upstream source for Stream_B.

Permissions Required on the Target Cluster

To run this command, your user ID must have the following permissions:

readAce and writeAce on the volume

adminperm permission on the source stream

Note: The mapr user is not treated as a superuser. HPE Ezmeral Data Fabric Event Store does not allow the mapr user to run this command unless that user is given the relevant permission or permissions with access-control expressions.
