Re: Nodetool cleanup error - cannot run before a node has joined the ring


Thank you Michael.

Well, this was apparently my bad.

1. nodetool connects to the local JMX port 7199, which is indeed running on localhost in my case.

2. I did a few more attempts, the message "Aborted cleaning up atleast one column family in keyspace <mykeyspace1>" only appears in the DC where <mykeyspace1> is not replicated, so it is indeed correct. I guess that the "Cleanup cannot run before a node has joined the ring" message refers to this.

3. I have seen a few log lines from CompactionManager.java showing nodetool cleanup doing work, so that's good. I guess that the "No sstables for <keyspace>.<table>" log lines refer to the fact that there is no sstable *to cleanup* for that table, not that it couldn't find any sstable.

So at the end of the day, just log messages that were not very clear (at least to me).

Thanks,

By default, yes, nodetool connects to localhost, which your log entries
show. Use `nodetool -h $PRIV_IP cleanup ...` to connect to that private
IP it's listening on. `nodetool help cleanup` for all options.
