CC @abstractdog , ready for review

[abstractdog]

LGTM

https://github.com/apache/hadoop/blob/767c9da6f34f9ed57311ba9f43497563c05b9f46/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/http/HttpServer2.java#L1730

apparently, unless the "requires admin" config is set explicitly to true, it's going to keep on working, but this way, cluster administrators have the chance to protect this endpoint

oh, 1 more thing, sorry @Aggarwal-Raghav , I can see the introduced code is sligtly different from the one in ProfileServlet, can you please unify those? (e.g. exact same message, maybe even a public constant)

tez/tez-common/src/main/java/org/apache/tez/common/web/ProfileServlet.java

Lines 166 to 168 in 0f389d2

	response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
	setResponseHeader(response);
	out.println("Unauthorized: Instrumentation access is not allowed!");

@abstractdog , I was planning to do major refactor as part of #527 but the comments are valid for this PR. Will address

[Aggarwal-Raghav]

For some reason in this PR, CI is failing, re-triggered it

[Aggarwal-Raghav]

Looks some jenkins agent / node issue

[Aggarwal-Raghav]

hadoop16 node/agent seems to be problematic. Run 1,4, 5 all failed on that.
