Subject [jira] [Commented] (YARN-1449) AM-NM protocol changes to support container resizing
Date Mon, 13 Jul 2015 22:10:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-1449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14625459#comment-14625459
] 

Jian He commented on YARN-1449:
-------------------------------

bq. because it may need to create the this.containersToIncrease if it is null.
If this.containersToIncrease is null, wont this call return upfront  ?
{code}
if (containersToIncrease == null) {
      return;
    }
{code}
bq. The AllocateRequestPBImpl.setAskList() uses the same logic.
Actually, many places use this logic. No need to respect that. The PB implementations are
often past-and-copy code that people pay less attention to it.
