Naganarasimha G R updated YARN-2495:
------------------------------------
Attachment: YARN-2495.20150318-1.patch
Hi [~wangda],
Thanks for finalizing the solution ,
+1 for use of {{NodeIdToLabelsProto}}, i have incorporated this in the patch
but ensured that interface will have set and get NodeLabels in
NodeHeartbeatRequest and RegisterNodeManagerRequest but manipulate in PBImpl's
such that NodeIdToLabelsProto is communicated across. So NodeLabelsSet will be
null if no labels are sent across.
+1 for handling of "Regarding the invalid node label issue of
registration/hearbeating" , Making the node labels empty will ensure that based
on old labels, scheduler will not wrongly allocate. But as part of this patch
will be only handling the logging of invalid labels in NM and RM. WebUI
updation and setting the node labels empty will be handled as part of new
jira, as this jira is becoming bulkier
I have incorporated other review comments (including the NM and
NodeStatusUpdateImpl modifications wrt Wangda's comments)
> Allow admin specify labels from each NM (Distributed configuration)

> Target of this JIRA is to allow admin specify labels in each NM, this covers
> - User can set labels in each NM (by setting yarn-site.xml (YARN-2923) or
> using script suggested by [~aw] (YARN-2729) )
> - NM will send labels to RM via ResourceTracker API
> - RM will set labels in NodeLabelManager when NM register/update labels
