Bikas Saha created YARN-450:
-------------------------------
Summary: Define value for * in the scheduling protocol
Key: YARN-450
URL: https://issues.apache.org/jira/browse/YARN-450
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Bikas Saha
Assignee: Zhijie Shen
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.
