Yuanbo Liu commented on HADOOP-13707: ------------------------------------- [~eyang] Really sorry for not pointing out trunk patch and branch-2.8/branch-2 patch are slightly different because of {{MetricsServlet.java}}. My patches in the attachment contain some changes about {{MetricsServlet.java}}. Hope my mistake won't bother you too much!
