--------------------------------
Summary: Add support for aborting a config-change operation that
cannot commit
Key: KUDU-1668
URL: https://issues.apache.org/jira/browse/KUDU-1668
Project: Kudu
Issue Type: Bug
Components: consensus
Reporter: Mike Percy
It would be helpful from an availability perspective to allow aborting a failed
config-change operation.
This requires some careful thought to determine a safe design but some options
might include:
* Allow a second concurrent config change operation to proceed if it reverts
the "active" config to the "committed" config
* If the config change fails, have the leader attempt to rev the term and push
a new NO_OP OpId with the same log index as the config change but a new term.
