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

bq. The jobconf should have mapreduce.job.tags - the JHS should be able read it from jobconf.

Make sense.

bq. For finished jobs, we should probably do it after JHS-related changes?

Yes, let's postpone it until JHS can work with tags.
