Peter Bacsko commented on YARN-9920:
------------------------------------
Thanks for patch [~prabhujoseph], looks pretty good. I have only minor comments.
1. Very nit: Docs should say "*Returns* the caller's remote ip address"
{noformat}
/**
* The caller's remote ip address.
* @return the caller's remote ip address.
*/
String getRemoteAddress();
{noformat}
2. {{Queue.java}} is an interface. The javadoc is completely missing for
{{hasAccess()}}. If you're at it, could you please add Javadoc for this method?
3. Similar here, Javadoc is incomplete for {{checkAccess()}, pls add some
description to the new as well as existing fields:
{noformat}

boolean checkAccess(UserGroupInformation callerUGI,

4. Ditto for {{CSQueue.java}}

+ public boolean hasAccess(QueueACL acl, UserGroupInformation user,
+ String remoteAddress, List<String> forwardedAddresses);
{noformat}
5. I can see you added a couple of new tests. But, is this code path covered
properly?
{noformat}
List<String> forwardedAddresses = null;
String forwardedFor = hsr.getHeader(RMWSConsts.FORWARDED_FOR);
if (forwardedFor != null) {
forwardedAddresses = Arrays.asList(forwardedFor.split(","));
}

> YarnAuthorizationProvider AccessRequest has null RemoteAddress in case of
> FairScheduler. FSQueue#hasAccess uses Server.getRemoteAddress() which will be
> null when the call is from RMWebServices and EventDispatcher. It works fine
> when called by IPC Server Handler.
> FSQueue#hasAccess is called at three places where (2) and (3) returns null.
> *1. IPC Server -> RMAppManager#createAndPopulateNewRMApp -> FSQueue#hasAccess
> -> Server.getRemoteAddress returns correct Remote IP.*
>
> *2. IPC Server -> RMAppManager#createAndPopulateNewRMApp ->
> AppAddedSchedulerEvent*
> *EventDispatcher -> FairScheduler#addApplication -> FSQueue.hasAccess ->
> Server.getRemoteAddress returns null*
