How can I find the reason on why the reduce copier failed?

Again I got the same error and it says
The reducer copier failed
...
could not find any valid local directory for file
/tmp/hadoop-hadoop/map_150.out
Searching the web shows that I have to clean up the /tmp/hadoop-hadoop folder
but the total size of this folder is 800KB with 1100 files.
, then this may have been a transient
issue. Worth investigating either way.
