Issue

A topology that previously existed and had nodes under it is not in use any more. The nodes under it have been moved out to a different topology or removed from the cluster entirely. But the topology would still be shown in the MCS UI. Is there any way to remove topology structure that no longer have any nodes in it?

Environment

This applies to all versions of the mapr server software.

Resolution

Currently there is no mechanism to remove an empty topology from UI/CLI. The CLDB automatically clears an empty topology after it's next restart or when there's a CLDB master fail over to an another node.
