Paulo Motta commented on CASSANDRA-16290: ----------------------------------------- bq. we should also fix it in 3.0 and 3.11 +1 > Consistency can be violated when bootstrap or decommission is resumed after > node restart > ---------------------------------------------------------------------------------------- > > 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 > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
