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.
