Ravi Prakash commented on HADOOP-7664:
--------------------------------------
Thanks Harsh! :)
Users usually tend to use the same config files as were used to start up the
cluster. Ideally they should have two different config files, one for bringing
up the cluster. And another for submitting jobs. Unfortunately that is
cumbersome.
I think the point of throwing a warning though is that some configuration which
the user wanted to set was not able to be set and as a consequence their job
might behave differently. If the value of the setting was already what the user
wanted, she/he does not need notification in my opinion.
> o.a.h.conf.Configuration complains of overriding final parameter even if the
> value with which its attempting to override is the same.
