Subject [jira] [Commented] (YARN-3866) AM-RM protocol changes to support container resizing
Date Thu, 08 Dec 2016 05:19:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-3866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15731145#comment-15731145
] 

Jian He commented on YARN-3866:
-------------------------------

IIUC, the value of adding back this API is to avoid the UnknownMethodException in java, app-writer
who mistakenly intended to use this API/feature has to revisit their code anyway...because
the API/feature was not complete. 
Anyway, if we agree to add back this API, I think we can only add the plain methods in the
class. No need to add to the proto definition, as it's just a useless payload sent to the
RM. Also, only add to 2.8, no need to add to trunk ?
