Subject [jira] [Commented] (CASSANDRA-12212) system.compactions_in_progress needs to be used on first upgrade to 3.0
Date Mon, 01 Aug 2016 07:49:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15401670#comment-15401670

Stefania commented on CASSANDRA-12212:
--------------------------------------

Thanks for clarifying. If I understood correctly, given that when local shards get reconciled
with global shards we take the global shard, and counter mutations in 2.1+ create global shards,
we shouldn't have any compactions in progress that need to reconcile two local shards unless
people have been using 2.1 only for a very short period of time. So the only legitimate case
would be the case when 2.1 is installed as an intermediate release before upgrading to 3.0.
Is this accurate?

> CASSANDRA-7066 removed the system.compactions_in_progress table and replaced it with
the new transaction system.  But system.compactions_in_progress needs to be consulted for
the first startup after upgrading from 2.1 to 3.0.
