Setting this property creates a tmp directory in BOTH local and HDFS.

It does so in HDFS because other properties use hadoop.tmp.dir as a base path to store data in HDFS. Example: dfs.name.dir=${hadoop.tmp.dir}/dfs/name creates this path in hdfs.

There is no way to have this property NOT create a path locally.
