Subject [jira] [Commented] (CASSANDRA-8734) Expose commit log archive status
Date Tue, 17 Feb 2015 17:54:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14324555#comment-14324555

Joshua McKenzie commented on CASSANDRA-8734:
--------------------------------------------

It's a bean modification w/read-only and a touch of scope change - I'm comfortable adding
this to 2.0.

Code LGTM - could you rebase to 2.0 [~cnlwsu]?  I'll get it committed as soon as we have a
2.0 version and merge it up.

> The operational procedure to modify commit log archiving is to edit commitlog_archiving.properties
and then perform a restart.  However this has troublesome edge cases:
> 1) It is possible for people to modify commitlog_archiving.properties but then not perform
a restart
> 2) It is possible for people to modify commitlog_archiving.properties only on some nodes
> 3) It is possible for people to have modified file + restart but then later add more
nodes without correct modifications.
> Because of these reasons, it is operationally useful to be able to audit the commit log
archive state of a node.  Simply parsing commitlog_archiving.properties is insufficient due
to #1.  
> I would suggest exposing either via some system table or JMX would be useful.
