> {{MRExecutor#pollInterval}} is currently hard coded to 50..1_000 for local
> mode and 500..10_000 otherwise. While being a sensible trade-off, one might
> want to poll more aggressively. For example, 1 seconds is usually too high
> for small integration tests.
> A few experiments on internal test suites showed that lowering poll interval
> could halve execution time.
> What do you think about adding a new configuration parameter that would
> override default config? I can craft a patch if needed.
