Subject [jira] [Commented] (YARN-1197) Support changing resources of an allocated container
Date Mon, 25 Nov 2013 19:46:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-1197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13831835#comment-13831835

Bikas Saha commented on YARN-1197:

This is great. However, for efficient review/commit we will need to break these down into
different jiras and attach patches to them. That will force us to look at each change by itself
(using this jira for context) and more importantly, make sure each logically distinct piece
is complete in itself. It should have its own tests, and pass Jenkins build/test independently
so that it can be committed independently. 
Can you please do that and determine the order in which those jiras should be reviewed/committed.
e.g. the API and protobuf changes should be a separate jira for RM and NM protocols. That
should probably be the first jira we should review. And so on.

> Currently, YARN cannot support merge several containers in one node to a big container,
which can make us incrementally ask resources, merge them to a bigger one, and launch our
processes. The user scenario is described in the comments.
