Subject [jira] [Commented] (YARN-289) Fair scheduler doesn't satisfy smaller request when bigger one is outstanding
Date Mon, 24 Dec 2012 23:18:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13539339#comment-13539339
] 

Bikas Saha commented on YARN-289:
---------------------------------

Could it be that 2048 request got "reserved" onto that node and that prevented the 1024 request
from being assigned to that node?

> An application requests a container with 1024 MB.  It then requests a container with
2048 MB.  A node shows up with 1024 MB available.  Even if the application is the only one
running, neither request will be scheduled on it.
