Subject [jira] [Updated] (YARN-450) Define value for * in the scheduling protocol
Date Wed, 06 Mar 2013 22:00:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhijie Shen updated YARN-450:
-----------------------------

    Attachment: YARN-450_2.patch

Please see the newer patch, where ANY = "*" has been moved to ResourceRequest that is part
of YARN API. Hence there's no need to add the dependency in pom.xml.

Btw, it seems that in protobuf, it is still unable to define static field. See https://code.google.com/p/protobuf/issues/detail?id=60

> 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.
