Subject [jira] [Commented] (YARN-5015) Support sliding window retry capability for container restart
Date Thu, 08 Mar 2018 04:34:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-5015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16390735#comment-16390735

Chandni Singh commented on YARN-5015:
-------------------------------------

@[~leftnoteasy] You are correct that this logic is only needed in the NM. I re-examined the
changes in YARN-611 and realized it is not needed outside of NM.

I will move it.

> We support sliding window retry policy for AM restarts (Introduced in YARN-611). Similar
sliding window retry policy is needed for container restarts.
> With this change, we can introduce a common class for SlidingWindowRetryPolicy ( suggested
by [~vvasudev] in the comments) and integrate it to container restart. 
> In a subsequent jira, we can modify the AM code to use SlidingWindowRetryPolicy which
will unify the AM and container restart code.
