>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: datanode
>            Reporter: Liangjun He

>            Priority: Minor
>              Labels: pull-request-available
>
> When optimizing the thread number of high-density storage DN, we found the 
> number of worker threads for the DataNode httpServer is twice the number of 
> available cores on node , resulting in too many threads. We can change this 
> to be configurable.
