Subject Re: Does HDFS have a temp directory?
Date Thu, 15 May 2014 11:45:34 GMT
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}
