Subject [jira] [Updated] (CASSANDRA-4880) Endless loop flushing+compacting system/schema_keyspaces and system/schema_columnfamilies
Date Wed, 14 Nov 2012 22:16:13 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4880?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pavel Yaskevich updated CASSANDRA-4880:
---------------------------------------

    Attachment: CASSANDRA-4880.patch

I made start timestamp schema timestamp repair account and fix any timestamps that are grater
than current timestamp and introduced new version in MessagingVersion as it's the only way
to fix infinite loop in schema due to broken nano timestamps that we can't properly fix in
<= 1.1.6.
