MapReduce job not running - i think i keep all correct configuration.
Hi all,
first i have a machine with all the demons are running on it. after that i
added two data nodes. In this case MR job working fine.
Now i changed the first machine to just namenode by stopping all the demons
except NN demon. and changed i data node to (SNN.JT,DN,TT) and all are
working. i keep the other data node like that only.
I changed the configurations to link up the NN and JT.
>From here when i tried to run MR job this is not running ..
Please help Me. Thanks
