Memory Total is not refreshed until an app is launched
------------------------------------------------------
Key: MAPREDUCE-3747
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3747
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.1
Reporter: Ramya Sunil
Fix For: 0.23.1
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.
