Summary: Add Tool to Perform Ring Membership Changes
Key: CASSANDRA-16140
URL: https://issues.apache.org/jira/browse/CASSANDRA-16140
Project: Cassandra
Issue Type: Improvement
Components: Cluster/Membership, Tool/nodetool
Reporter: Paulo Motta
It would be nice to provide a specific tool (ie. ringtool) to allow operators
to perform safe ring membership operations (CASSANDRA-16139) such as removing
failed nodes, aborting failed ring update proposals, adding or removing tokens
to a host, moving tokens etc.
While we could provide this functionality via nodetool as done currently, I
think it would be better to have an exclusive tool for this to separate
concerns. Furthermore we can add specific permissions to this tool that are
different from nodetool to allow only authorized operators to perform ring
membership changes.
We should support the current methods available on nodetool (such as nodetool
move, nodetool join, nodetool bootstrap resume, etc) and deprecate them on
nodetool asking users to use the new tool moving forward.
