Subject [jira] [Commented] (MAPREDUCE-2738) Missing cluster level stats on the RM UI
Date Tue, 04 Oct 2011 14:50:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2738?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13120180#comment-13120180
] 

Robert Joseph Evans commented on MAPREDUCE-2738:
------------------------------------------------

I can change it to good and removed, but that is not what was listed previously in the web
UI.  Our ops team wants to know how many nodes were blacklisted vs. excluded at a glance,
and not have to do that calculation themselves so I would prefer to keep blacklisted vs. excluded.

Everything else should be doable.  I will have an updated patch soon.

> Cluster usage information such as the following are currently not available in the RM
UI. 
> - Total number of apps submitted so far
> - Total number of containers running/total memory usage 
> - Total capacity of the cluster (in terms of memory)
> - Reserved memory
> - Total number of NMs - sorting based on Node IDs is an option but when there are lost
NMs or restarted NMs, the node ids does not correspond to the actual value
> - Blacklisted NMs - sorting based on health-status and counting manually is not very
straight forward
> - Excluded NMs
> - Handle to the jobhistory server
