Chris Nauroth commented on HDFS-5336:
-------------------------------------
Thanks for the patch, Akira. I built and verified that startup progress
metrics only showed up in namenode and not datanode.
bq. Change the context of the startup metrics from 'default' to 'dfs'.
Unfortunately, I think this would be backwards-incompatible. For example, if
someone was using metrics filtering, then their filtering configuration under
the old context would stop working. Can we please remove this part of the
change?
