[jira] [Commented] (YARN-4170) AM need to be notified with priority in AllocateResponse

    [ https://issues.apache.org/jira/browse/YARN-4170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14941270#comment-14941270 ] 

Rohith Sharma K S commented on YARN-4170:
-----------------------------------------

Currently for every AM heartbeat, Priority has been sent back to AM in AllocateResponse. Instead of sending same priority in every heartbeat, let send priority only if priority has been updated?

> As discussed in MAPREDUCE-5870, Application Master need to be notified with priority in Allocate heartbeat.  This will help AM to know the priority and can update JobStatus when client asks.
