Subject [jira] [Commented] (CASSANDRA-6463) cleanup causes permission problems
Date Tue, 07 Jan 2014 23:15:50 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13864837#comment-13864837

Aleksey Yeschenko commented on CASSANDRA-6463:
----------------------------------------------

Can't say, b/c I don't know what caused the issue in the first place. A topology change? Increasing
RF on system_auth without running repair afterwards?

Either way, just run repair on every node (just for the system_auth keyspace) - it won't take
much time.

> After a cleanup I loose permissions (f.e. SELECT, MODIFY). When I listed the system_auth/permissions
CF after cleanup I recognized, around the half of all permissions lost - BUT: If I list the
permissions table with consistency ALL, all entries appear again and my programm continues
working. Only if I manual trigger that read-repair! That tells me indirect, that system_auth
is reading using consistency ONE, what causes problems after cleanup (?). A good approach
(?) could be to re-read system_auth after permission fail with consistency > ONE to trigger
read-repair once and keep speed.
