Karthik Kambatla commented on YARN-1867:
Good catch. The fix looks good to me.
bq. The code in the main ResourceManager has become unmaintenable after the
introduction of the active-services.
Agree. I have been thinking of it too. I think we should just move
RMActiveServices into its own file - that would force us to clean up the
unwieldy mess it has become. Filed YARN-1874 to do the same. Feel free to pick
it up. I can take a stab, may be in a week or two.
That said, it would be nice to address all the cleanup changes there,
particularly if they are not related to the bug we are fixing here.

Also, we should probably limit the formatting changes to the files that have
non-formatting changes. May be leave out RMContextImpl?

bq. A little bit of cleanup per patch should be okay. I'd like to keep them
here unless you feel strongly that it is prohibiting the review.
I am not very particular about it - the patch is fairly small and those changes
don't get in the way of review. I am okay with leaving them in, if you insist.
My only concern is the git history wouldn't tell us why we made these changes
if we hide them behind a bug fix.

Karthik Kambatla commented on YARN-1867:
It appears the RM doesn't have the ACLs corresponding to an application from
{{RMContext#getRMApps()}}. We couldn't reproduce this. The cluster had RM
failover with app recovery.
Couldn't identify the source of this through visual inspection. This can happen
when the RM goes down (or restarted, or failed over) between adding the app and
adding the ACLs for the app. If that were the case, I see the following
solutions:
# If ACLs are not available, use the default value.
# Reverse the order of adding an app to ACLsManager and RMContext.

That doesn't sound right. When RM recovers, it just simply puts the app back
into *both* the context and the acls manager. Can you debug more?
