your tasks are running out of memory you can increase memory by setting
property
*mapred.child.java.opts *-Xmx500m
this means your tasks (map/reduce) can use maximum of 500 MB memory. default
is 200m.
increase it as much as you physical memory allows using swap space will make
processing slow.

Hi,
Please check the namenode heap usage. Your cluster may be having too many files
to handle / too little free space. It is generally available in the UI. This is
one of the causes I have seen for the Timeout.
