["Paulo Motta (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-3486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15182995#comment-15182995 ] 

Paulo Motta commented on CASSANDRA-3486:
----------------------------------------

[~jasobrown] do you still plan to work on this? There is a lot of overlap between this and CASSANDRA-11190, which I'll start working on it soon, so I wanted to check if we could still reuse anything of your first draft or better start from scratch.

As to your previous questions, I think we can provide a way for users to stop/abort an ongoing local repair session given its session id. So, if session <id> is happening on nodes A, B and C, I can execute {{nodetool repair --abort <id>}} on nodes A, B or C to abort session <id>. I if execute {{nodetool repair --abort <id>}} on node D, it will print something like {{No ongoing repair session found with id <id>}}. For this to be useful, we should also provide a {{nodetool repair --list}} command to list ongoing repair sessions on the local node, and also {{nodetool repair --abort-all}} to abort all ongoing sessions on the local node.
