Removing Upstream Sources for a Stream

You can un-register a stream as an upstream source for a stream using the MCS and the CLI. When you remove a stream as an upstream source for a stream, the upstream source stream will stop sending updates to the stream.

Removing Upstream Sources for a Stream Using the MapR Control System

  1. Log in to MCS and go the Replication tab in the stream information page.
  2. Select the upstream sources to remove in the Upstream Sources pane and click Remove Upstream Source(s).
    The Remove Upstream Source(s) confirmation window displays.
  3. Verify the list and click Remove Upstream Source.
    This action un-registers the selected stream(s) as upstream source(s) for this stream.

Removing Upstream Sources for a Stream Using the CLI or REST API

The command to decouple upstream sources is:
