Jian Fang commented on MAPREDUCE-6304:
--------------------------------------
YarnRunner is the right place to set the labels for a MR job. However, there is
one concern here. If I understand correctly, YarnRunner runs at the job client
side, right? There should also be a way to hook in the labels on the server
side, i.e., resource manager side. The reason is that many Hadoop users do not
understand or set the labels by themselves and they simply rely on the Hadoop
platform provider (or system admins for on-premise clusters) to set up the
labels for them. I am not sure if this is a general use case, but it is
definitely a feature that we need.
