shanyu zhao commented on HADOOP-10178:
--------------------------------------
Thanks [~tucu00] for reviewing! As for the renaming of the source message, I
think you don't need to call out "using BB" because the property name is BB, so
that "using BB" is implied. This means the "source" that set the BB property in
configuration is "because CC is deprecated".
> Configuration deprecation always emit "deprecated" warnings when a new key is
> used

> Even if you use any new configuration properties, you still find "deprecated"
> warnings in your logs. E.g.:
> 13/12/14 01:00:51 INFO Configuration.deprecation: mapred.input.dir.recursive
> is deprecated. Instead, use
> mapreduce.input.fileinputformat.input.dir.recursive
