Zhijie Shen commented on MAPREDUCE-5699:
----------------------------------------

In addition to pass tags when being submitted to YARN, should we make the 
running MRAppMaster/Job remember the tags as well. One of reason is that we 
need to parse them to JHS as the requirement of MAPREDUCE-5658.

Another thing I'm considering is whether we'd like to support more features 
that are made possible by tags. For example, JobClient can also filter 
applications by tags. Thoughts?
