Subject [jira] [Commented] (MAPREDUCE-6304) Specifying node labels when submitting MR jobs

Naganarasimha G R commented on MAPREDUCE-6304:
----------------------------------------------

[~john.jian.fang], thanks for the comments but did not get your idea completely. Comment is
for the approach taken in the patch or earlier discussion of supporting default label expression
for am container ?
bq. The default decorator from Apache does nothing, but hadoop allows users to use a custom
decorator from hadoop configuration.
Can you please specify which configuration you are referring to ?
