> In our production environment, when DN needs to delete a large number blocks,
> we find that many deletion tasks are backlogged in the queue of
> threadPoolExecutor in FsDatasetAsyncDiskService. We can't improve its
> throughput because the number of core threads is hard coded.
> So DN needs to support the number of core threads of
> FsDatasetAsyncDiskService can be configured.
