hadoop.tmp.dir is used as the temporary directories in HDFS.
for the mapreduce processing there is mapred.system.dir is set by default
to "${hadoop.tmp.dir}/mapred/system" where the mapreduce framework stores
system files.
if you dont want to tied the hdfs temp and mapreduce temp then you can edit
mapred-site.xml such a way that mapred.system.dir is not tied to
${hadoop.tmp.dir}
