> The current {{NetworkEnvironment}} would be the default {{ShuffleService}}
> implementation in task manager. In order to make the interface simple, we try
> to avoid more interactive with {{NetworkEnvironment}}.
> {{NetworkEnvironment#unregisterTask}} is used for closing partition/gate and
> releasing partition from {{ResultPartitionManager}}. partition/gate close
> could be done in task which already maintains the arrays of them. Further we
> could release partition from {{ResultPartitionManager}} inside
> {{ResultPartition}} via introducing {{ResultPartition#close(Throwable)}}. To
> do so, the {{NetworkEnvironment#unregisterTask}} could be totally replaced to
> remove.
