Grant Henke updated KUDU-2915:
------------------------------
Labels: supportability (was: )
> Support to delete dead tservers from CLI
> ----------------------------------------
>
> Key: KUDU-2915
> URL: https://issues.apache.org/jira/browse/KUDU-2915
> Project: Kudu
> Issue Type: Improvement
> Components: CLI, ops-tooling
> Affects Versions: 1.10.0
> Reporter: Hexin
> Assignee: Hexin
> Priority: Major
> Labels: supportability
>
> Sometimes the nodes in the cluster will crash due to machine problems such as
> disk corruption, which can be very common. However, if there are some dead
> tservers, ksck result will always show error (e.g. Not all Tablet Servers are
> reachable) although all tables have recovered to be healthy.
> The only way now to get the healthy status of ksck is to restart all masters
> one by one. In some cases, for example, if the machine has completely
> corrupted, we hope to get healthy status of ksck without restarting, since
> after restarting masters the cluster will take some time to recover, during
> which it will have influence on scanning or upsetting to tables. The recovery
> time can be long which mainly depends on the scale of cluster. This problem
> can be serious and annoying especially tservers crashed with high-frequency
> in a large cluster.
> It’s valuable if we have an easier way to delete dead tservers from master, I
> will support a kudu command to realize it.
