Subject [jira] [Commented] (YARN-4081) Add support for multiple resource types in the Resource class
Date Thu, 27 Aug 2015 03:04:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14715991#comment-14715991

Srikanth Kandula commented on YARN-4081:

Extending to multiple resources is great, but why use a Map? Is there a rough idea how many
different resources one may want to encode? It seems an overkill to incur so much additional
overhead if say all that is needed is a handful of more resources. Ditto for encapsulating
strings in URIs and the ResourceInformation wrapper over doubles. It would perhaps have been
okay if this datastructure was less often used but if i understand correctly, Resources is
created/destroyed at least once per ask/ assignment and often many more times...
