Attachment: HDFS-13272.000.patch
> Reduce the HttpServer2 thread count on DataNodes
> ------------------------------------------------

> Key: HDFS-13493
> URL: https://issues.apache.org/jira/browse/HDFS-13493
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Reporter: Erik Krogen
> Assignee: Erik Krogen
> Priority: Major
> Attachments: HDFS-13272.000.patch
>
>
> Given that HFTP was removed in Hadoop 3 and WebHDFS is handled via Netty, the
> HttpServer2 instance within the DataNode is only used for very basic tasks
> such as the web UI. Thus we can safely reduce the thread count used here.
