Subject: Re: reference document which properties are set in which
 configuration file

As a thumb rule, all properties starting with mapred.* or mapreduce.*
go to mapred-site.xml, all properties starting with dfs.* go to
hdfs-site.xml, and the rest may be put in core-site.xml to be safe.

In case you notice MR or HDFS specific properties being outside of
this naming convention, please do report a JIRA so we can deprecate
the old name and rename it with a more appropriate prefix.
