> Allow WebHDFSClient to reuse HTTP connections (HTTP Keep-Alive)

> Key: HDFS-11280
> URL: https://issues.apache.org/jira/browse/HDFS-11280
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 2.7.3, 2.6.5, 3.0.0-alpha1
> Reporter: Zheng Shao
> Assignee: Zheng Shao
> Attachments: HDFS-11280.for.2.7.and.below.patch,
> HDFS-11280.for.2.8.and.beyond.patch
>
>
> WebHDFSClient calls "conn.disconnect()", which disconnects from the NameNode.
> When we use webhdfs as the source in distcp, this used up all ephemeral
> ports since all closed connections continue to occupy the port with TIME_WAIT
> status for some time.
> According to http://tinyurl.com/java7-http-keepalive, we should call
> conn.getInputStream().close() instead to make sure the connection is kept
> alive. This will get rid of the ephemeral port problem.
> Reference:
