Subject [jira] [Commented] (CASSANDRA-7124) Use JMX Notifications to Indicate Success/Failure of Long-Running Operations
Date Mon, 10 Nov 2014 20:24:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14205273#comment-14205273

Rajanarayanan Thottuvaikkatumana commented on CASSANDRA-7124:
-------------------------------------------------------------

[~thobbs] I have done the first cut of changes for the JMX notifications for the "cleanup"
command. Here are the things I have done
1) Implemented an abstract Runner class
2) Inherited the CleanupRunner from Runner and implemented the "run" method specific to the
"cleanup"
3) In the NodeProbe.java class implemented a cleanupAsync method with the JMX related changes
4) In the NodeTool.java, the newly added method is called

I have done the clean compilation and other sanity tests related to the changes. How do I
test it, should you want to have a look at the changes done? In that case should I upload
a temporary patch? Please let me know. Thanks

> If {{nodetool cleanup}} or some other long-running operation takes too long to complete,
you'll see an error like the one in CASSANDRA-2126, so you can't tell if the operation completed
successfully or not.  CASSANDRA-4767 fixed this for repairs with JMX notifications.  We should
do something similar for nodetool cleanup, compact, decommission, move, relocate, etc.
