running compaction from a machine outside the cluster

[Anurag Gujral <an...@gmail.com>]

Hi All,
         Is there a way I can run compaction on the cassandra cluster from a
machine where cassandra is not installed.I have a cluster of 6 machines
but I want to run compaction on them from a different machine which does not
have cassandra installed.

Thanks
Anurag

If you can reach your jmx ip/port, you can use any jmx client to start a
compaction. Use jconsole to connect to your jmx ip/port and then navigate to
mbeans->org.apache.cassandra.db->columnfamilies->.... ->operations

Underneath there you can invoke a bunch of methods including compaction.

"nodetool -h your-remote-host compact", assuming firewall allows.
Unless "does not have cassandra installed" means that you can't use
nodetool either?
