Brahma Reddy Battula commented on HDFS-8572:
--------------------------------------------
HI [~wheat9]
while committing this patch,do you remove following purposefully in branch-2..?
{code}
- this.infoServer.addInternalServlet(null, "/streamFile/*",
StreamFile.class);
- this.infoServer.addInternalServlet(null, "/getFileChecksum/*",
- FileChecksumServlets.GetServlet.class);
{code}
I think ,distcp will fail when we use hftp since it expect streamFile and throw
following error..am I correct..? if you agree with me,would like raise separate
jira and add back...

> In HDFS-7279 the Netty server in DN proxies all servlet requests to the local
> Jetty instance.
> The Jetty server is configured incorrectly so that it always uses
> {{HTTP/locahost@REALM}} to authenticate spnego requests. As a result,
> servlets like JMX are no longer accessible in secure deployments.
