Subject [jira] [Commented] (YARN-396) Rationalize AllocateResponse in RM scheduler API
Date Wed, 19 Mar 2014 02:17:48 GMT

    @tgravescs FWIW I think something like this is the case, yes. The change happened in https://issues.apache.org/jira/browse/YARN-396
which occurred for the first(?) YARN TLP release with Hadoop 2.1. And CDH 4.4 was the first
release I see that picked up this change. I assume it was useful/necessary to float this 'alpha'
API ahead.
    
    I also would have thought it's possible the `yarn` profile works with this release, but
I do not know. Just making sure that has been tried?
    
    Otherwise yeah it looks like a question of supporting another intermediate flavor of YARN
here since it did change in breaking ways several times between 0.23.x and 2.2

> AllocateResponse contains an AMResponse and cluster node count. AMResponse that more
data. Unless there is a good reason for this object structure, there should be either AMResponse
or AllocateResponse.
