> Key: KUDU-3585
> URL: https://issues.apache.org/jira/browse/KUDU-3585
> Project: Kudu
> Issue Type: Sub-task
> Components: client, test
> Affects Versions: 1.14.0, 1.15.0, 1.16.0, 1.17.0

> The scenario sometimes fails in TSAN builds with output like cited below.
> It seems the root cause was RPC queue overflows at kudu-master and
> kudu-tserver: both spend much more time on regular requests when built with
> TSAN instrumentation, and resetting the client'ss meta-cache too often
> induces a lot of GetTableLocations requests, and serving eats a lot of CPU
> and many threads are kept busy. Since an internal mini-cluster is used in
> the scenario (i.e. all masters and tablet servers are a part of just one
> process), that affects kudu-tserver RPC worker threads as well, so many
> requests accumulate in the RPC queues.

> Expected: CheckNoRpcOverflow() doesn't generate new fatal failures in the

> Actual: it does.
