Subject [jira] [Updated] (YARN-2495) Allow admin specify labels from each NM (Distributed configuration)
Date Thu, 05 Mar 2015 17:48:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-2495?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Naganarasimha G R updated YARN-2495:
------------------------------------
    Attachment: YARN-2495.20150305-1.patch

Hi [~wangda],
Attaching a patch with following changes :
* ??Name changes is->are?? 
* ??Make RegisterNodeManagerRequest consist wiht NodeHeartbeatRequest?? 
* ??Change decentralized-configuration.enabled to input, accept value of <centralized,
distributed> (by default is centralized)??  
* ??you can leave an empty provider implementation?? : have taken care in the patch, please
check the approach
* ??stop NM if ResourceTrackerService informs it as invalid labels??  
* In Analogus to the issue mentioned by Vinod (stop NM if ResourceTrackerService informs it
as invalid labels), I feel even during registration RM should send out shutdown with proper
message. I have this handled in the patch
* RM on receiving invalid Labels for a node, it will set the state of RMNode as {{NodeState.UNHEALTHY}}
using a new event RMNodeInValidNodeLabelsUpdateEvent , please inform whether to create new
State or NodeState.UNHEALTHY should suffice.

Script related issued will discuss/fix in script jira (YARN-2729).
