Stefan Miklosovic commented on CASSANDRA-18555: ----------------------------------------------- [~chovatia.jayd...@gmail.com] [~maxwellguo] let me know what you think about this https://github.com/apache/cassandra/pull/2390 The idea is that DECOMISSION_FAILED will be written into system.local so you can just query it ... > A new nodetool/JMX command that tells whether node's decommission failed or > not > ------------------------------------------------------------------------------- > > Key: CASSANDRA-18555 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18555 > Project: Cassandra > Issue Type: Task > Components: Observability/JMX > Reporter: Jaydeepkumar Chovatia > Assignee: Jaydeepkumar Chovatia > Priority: Normal > Time Spent: 10m > Remaining Estimate: 0h > > Currently, when a node is being decommissioned and if any failure happens, > then an exception is thrown back to the caller. > But Cassandra's decommission takes considerable time ranging from minutes to > hours to days. There are various scenarios in that the caller may need to > probe the status again: > * The caller times out > * It is not possible to keep the caller hanging for such a long time > And If the caller does not know what happened internally, then it cannot > retry, etc., leading to other issues. > So, in this ticket, I am going to add a new nodetool/JMX command that can be > invoked by the caller anytime, and it will return the correct status. > It might look like a smaller change, but when we need to operate Cassandra at > scale in a large-scale fleet, then this becomes a bottleneck and require > constant operator intervention. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
