[jira] [Updated] (CASSANDRA-4767) Need some indication of node
repair success or failure
[ https://issues.apache.org/jira/browse/CASSANDRA-4767?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuki Morishita updated CASSANDRA-4767:
--------------------------------------
Attachment: 4767-1.1.txt
Patch attached to track repair progress by using JMX notification.
I made another JMX method forceTableRepairAsync, to invoke repair asynchronously, because I think we don't want to break existing API at the middle of 1.1 release.
StorageServiceMBean now has notification support, so we can use that to turn other long running JMX calls into async call and track progress as well in the future.
Repair command subscribes to JMX notification and invoke async repair, receives STARTED, and FINISHED event to determine command start and stop, as well as SUCCESS and FAILED to track status per repair session.
Sample output of 'nodetool repair' is as follows:

> We are currently verifying node repair status via basic log analysis. In order to automatically track the status of periodic node repair jobs, it would be better to have an indicator (through JMX perhaps).
