Description

This question/problem pops up all the time. Can we please eliminate hadoop.tmp.dir's usage from the default in dfs.data.dir. It is confusing to new people and results in all sorts of weird accidents. If we want the same value, fine, but there are a lot of implied things by the variable re-use.
