Work Description: ZanderXu opened a new pull request, #4360:
URL: https://github.com/apache/hadoop/pull/4360
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.
