Resolution: Invalid
Fix Version/s: 1.3.1
> Add tablet-specific version of MetaCacheServerPicker::MarkServerFailed()

> Key: KUDU-2023
> URL: https://issues.apache.org/jira/browse/KUDU-2023
> Project: Kudu
> Issue Type: Improvement
> Components: client
> Affects Versions: 1.4.0
> Reporter: Alexey Serbin
> Assignee: Alexey Serbin
> Fix For: 1.3.1
>
>
> -Current implementation of {{MetaCacheServerPicker::MarkServerFailed()}}
> marks the whole tablet server with multiple tablets as failed in the metadata
> cache, so future requests to any tablets hosted by the server would be
> directed to replicas hosted by other tablet servers. There are particular
> use-cases where having tablet-grained version of the
> {{MetaCacheServerPicker::MarkServerFailed()}} method would be beneficial.
> For example, marking only particular tablet failed on a tablet server because
> of an error during {{KuduSession::Flush()}} could avoid thrashing the whole
> metadata cache for the rest of tablets on the same server if the server is
> overall healthy and robust.-
> UPDATE: as it turned out, that was not correct --
> {{MetaCacheServerPicker::MarkServerFailed()}} marks as failed only tablet
> replicas on the specified server, not the whole server.
