> 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.
