> Leader replica sometimes reports follower's health status as FAILED instead
> of FAILED_UNRECOVERABLE
> ---------------------------------------------------------------------------------------------------

> Key: KUDU-2367
> URL: https://issues.apache.org/jira/browse/KUDU-2367
> Project: Kudu
> Issue Type: Bug
> Components: tserver
> Affects Versions: 1.7.0, 1.8.0
> Reporter: Alexey Serbin
> Assignee: Alexey Serbin
> Priority: Major
>
> If a leader tablet replica detects that its follower falls behind the WAL
> segment GC threshold after the unavailability interval (defined by the
> {{--follower_unavailable_considered_failed_sec}} flag), it never reports the
> status of the follower as FAILED_UNRECOVERABLE to the catalog manager, and
> continues reporting FAILED instead. In configurations where the tablet
> replication factor equals to the total number of tablet servers in the
> cluster, that leads to situations when the tablet cannot be automatically
> recovered for a long time. In particular, such situations last until a new
> leader is elected or corresponding tablet servers are restarted.
