Subject [jira] Updated: (CASSANDRA-1951) offline local nodes
Date Tue, 25 Jan 2011 12:32:44 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-1951?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne updated CASSANDRA-1951:
----------------------------------------

    Attachment: 0001-Allow-to-start-and-stop-the-thrift-server-through-JM.patch

Attached patch does the missing part, that is it allows to stop and restart the thrift server
(or avro, though I've tested the latter less extensively) from JMX. In addition, it allows
to not start the thrift server at boot time through -Dcassandra.start_rpc=false (in which
case it can be start through JMX).

Implementation note: the thrift server (connection accepting code) was running as the main
thread (serverEngine.server() was blocking) which didn't make this easily doable so the patch
change this and spawn a thread for the said connection acception code (Avro was already doing
this in a separate thread).

> We'd like the ability to take a node offline (gossip, thrift, etc), but without bringing
down cassandra.  The main reason is so that compactions can be performed completely off-line.
> CASSANDRA-1108 gets us most of the way there, but not all the way.
