["Vinod Kumar Vavilapalli (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-2005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15201146#comment-15201146 ] 

Vinod Kumar Vavilapalli commented on YARN-2005:
-----------------------------------------------

-1 for backporting this, while I understand that the original feature-ask is useful for avoiding AM scheduling getting blocked, there are far too many issues with the feature as it is. Please see my comments on YARN-4576 and YARN-4837.

> It would be nice if the RM supported blacklisting a node for an AM launch after the same node fails a configurable number of AM attempts.  This would be similar to the blacklisting support for scheduling task attempts in the MapReduce AM but for scheduling AM attempts on the RM side.
