[jira] [Commented] (YARN-450) Define value for * in the scheduling protocol

    [ https://issues.apache.org/jira/browse/YARN-450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13595091#comment-13595091 ] 

Bikas Saha commented on YARN-450:
---------------------------------

Do you mean org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNode? That class is not really part of the YARN API right? I guess thats why you are seeing dependency issues.
This official value would need to be part of the API. So ResourceRequest would be a good place.
A thing to explore would be if this can be defined in the proto definition of the API.

> The ResourceRequest has a string field to specify node/rack locations. For the cross-rack/cluster-wide location (ie when there is no locality constraint) the "*" string is used everywhere. However, its not defined anywhere and each piece of code either defines a local constant or uses the string literal. Defining "*" in the protocol and removing other local references from the code base will be good.
