-----------------------------------

Integrated in Hadoop-Common-trunk-Commit #1666 (See [https://builds.apache.org/job/Hadoop-Common-trunk-Commit/1666/])
    MAPREDUCE-3747. Initialize queue metrics upfront and added start/finish time to RM Web-UI.

> Memory Total on the RM UI is not refreshed until an application is launched. This is
a problem when the cluster is started for the first time or when there are any lost/decommissioned
NMs.
> When the cluster is started for the first time, Active Nodes is > 0 but the Memory
Total=0. Also when there are any lost/decommissioned nodes, Memory Total has wrong value.
> This is a useful tool for cluster admins and has to be updated correctly without having
the need to submit an app each time.
