Subject [jira] [Commented] (MAPREDUCE-5951) Add support for the YARN Shared Cache
Date Thu, 14 May 2015 01:02:01 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5951?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14543022#comment-14543022
] 

Chris Trezzo commented on MAPREDUCE-5951:
-----------------------------------------

Note for the above calculation: We can probably get rid of shortUserName from the resource
reference if we are not doing release calls. If that is the case, then the additional memory
should be even smaller.

> Implement the necessary changes so that the MapReduce application can leverage the new
YARN shared cache (i.e. YARN-1492).
> Specifically, allow per-job configuration so that MapReduce jobs can specify which set
of resources they would like to cache (i.e. jobjar, libjars, archives, files).
