[jira] [Created] (KUDU-1504) Add a tool to force a Raft config change

Mike Percy created KUDU-1504:
--------------------------------

             Summary: Add a tool to force a Raft config change
                 Key: KUDU-1504
                 URL: https://issues.apache.org/jira/browse/KUDU-1504
             Project: Kudu
          Issue Type: Bug
          Components: consensus, ops-tooling
    Affects Versions: 0.9.0
            Reporter: Mike Percy


It would be useful to implement a tool that allowed for an administrator-controlled "forced" configuration change. This type of thing is useful as a "parachute" if, for example, 2 nodes of a 3-node configuration were permanently offline. An administrator may wish to accept whatever potential data loss occurred and force the configuration to be composed of a single node so that it could come back online and then grown back to a larger configuration size again.
