>
> Key: CASSANDRA-16290
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16290
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Bootstrap and Decommission
> Reporter: Paulo Motta
> Assignee: Stefan Miklosovic
> Priority: Normal
> Fix For: 3.0.x, 3.11.x, 4.0-beta
>
>
> Since CASSANDRA-12008, successfully transferred ranges during decommission
> are saved on the {{system.transferred_ranges}} table. This allow skipping
> ranges already transferred when a failed decommission is retried with
> {{nodetool decommission}}.
> If instead of resuming the decommission, an operator restarts the node, waits
> N minutes and then performs a new decommission, the previously transferred
> ranges will be skipped during streaming, and any writes received by the
> decommissioned node during these N minutes will not be replicated to the new
> range owner, what violates consistency.
> This issue is analogous to the issue mentioned [on this
> comment|https://issues.apache.org/jira/browse/CASSANDRA-8838?focusedCommentId=16900234&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16900234]
> for resumable bootstrap (CASSANDRA-8838).
> In order to prevent consistency violations we should clear the
> {{system.transferred_ranges}} state during node restart, and maybe a system
> property to disable it. While we're at this, we should change the default of
> {{-Dcassandra.reset_bootstrap_progress}} to {{true}} to clear the
> {{system.available_ranges}} state by default when a bootstrapping node is
> restarted.
