> C++ client errors misreported as GetTableLocations timeouts
> -----------------------------------------------------------
>
> Key: KUDU-1466
> URL: https://issues.apache.org/jira/browse/KUDU-1466
> Project: Kudu
> Issue Type: Bug
> Components: client
> Affects Versions: 0.8.0
> Reporter: Todd Lipcon
> Assignee: Alexey Serbin
> Priority: Critical
>
> client-test is currently very flaky due to this issue:
> - we are injecting some kind of failure on the tablet server (eg DNS
> resolution failure)
> - when we fail to connect to the TS, we correctly re-trigger a lookup against
> the master
> - depending how the backoffs and retries line up, we sometimes end up
> triggering the lookup retry when the remaining operation budget is very short
> (eg <10ms)
> -- this GetTabletLocations RPC times out since the master is unable to
> respond within the ridiculously short timeout
> During the course of retrying some operation, we should probably not replace
> the 'last_error' with a master error, so long as we have had at least one
> successful master lookup (thus indicating that the master is not the problem)
