Does HDFS have a temp directory?
Hi Experts,
Does HDFS have a temp directory for general use like linux and what is the
strategy of deleting files in the temp directory?

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}
