Subject Aborting Map Function
Date Wed, 16 Apr 2008 15:28:30 GMT


I am developing one application with MapReduce and in that whenever some
MapTask condition is 
met, I would like to broadcast to all other MapTask to abort their work. I
am not quite sure whether
such broadcasting functionality currently exist in Hadoop MapReduce. Could
someone give some

Although extending this functionality may be easy as all the slaves
periodically ping the master,
I was just thinking of piggybacking one bit information from the slave to
the master and master
may send this information to all the slaves in the next round. Any
suggestions to this approach ?
