Grant Henke updated KUDU-2257: ------------------------------ Labels: supportability (was: ) > Add tool to recover a tablet that has lost a majority of replicas > ----------------------------------------------------------------- > > Key: KUDU-2257 > URL: https://issues.apache.org/jira/browse/KUDU-2257 > Project: Kudu > Issue Type: Improvement > Reporter: William Berkeley > Priority: Major > Labels: supportability > > In the unfortunate case where a tablet has lost a majority of its replicas, > the way to recover is to rewrite the config of the remaining healthy members > so the unhealthy members are excluded, then wait for normal re-replication. > This involves k similar commands on the k remaining healthy servers. We could > simplify the process by adding a simple tool "kudu tablet > unsafe_promote_minority" that does the rewrite in one step. > The tool could use ksck to try and identify the healthy minority, or it could > rely on the user to do that. > The tool should also make it very clear that it may cause data loss and that > its use is a last resort. -- This message was sent by Atlassian Jira (v8.3.4#803005)
