Hello, 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 hints.
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 ? Thanks.
