Description

On CapacityScheduler's web UI, AM usage of different users belong to the same queue always shows queue's AM usage.

The root cause is: under CapacitySchedulerPage.

        tbody.tr().td(userInfo.getUsername())
            .td(userInfo.getUserResourceLimit().toString())
            .td(resourcesUsed.toString())
            .td(resourceUsages.getAMLimit().toString())
            .td(amUsed.toString())
            .td(Integer.toString(userInfo.getNumActiveApplications()))
            .td(Integer.toString(userInfo.getNumPendingApplications()))._();

Instead of amUsed.toString(), it should use userInfo.getAmUsed().
