> hello，I have dwelled on this hadoop(cdhu3) problem for 2 days,I have tried
> every google method.This is the issue: when ran hadoop example "wordcount"
> ,the tasktracker's log in one slave node presented such errors
> 1.WARN org.apache.hadoop.mapred.DefaultTaskController: Task wrapper stderr:

> (No such file or directory)
> I could not find similar issues in google,just got some posts seem a little
> relevant ,which suggest: A. the ulimit of hadoop user----but my ulimit is set
> large enough for this bundled example;B. the memory used by jvm,but my jvm
> only use Xmx200m,too small to exceed the limit of my machine ;C.the privilege
> of the mapred.local.dir and logs dir----I set them by "chmod 777";D .the disk
> space is full----there are enough space for hadoop in my log directory and
> mapred.local.dir.
> Thanks for you all,I am really at my wit's end,I have spend days on it. I
> really appreciate any light!
