mapred-site.xml* and noting the same IP in *conf/masters* file? Do I need

the two

all communication regarding health of task tracker and tasks assigned to TT
from JT, info on failed tasks, completed all is communicated through

hi
the periodic heartbeat call that task trackers make to the jobtracker is
thru RPC same for namenode and data nodes.

hi,
i am trying to figure out how hadoop uses data locality to schedule maps on
nodes which locally store tha map input ... going through code i am going in

is to say that i cant locate the HDFS API or func that can commu
hi could anyone point me to where i can download the LATE scheduler API plug
in for HAdoop ... i distinctly remember reading up on work on the API in
this mailing list but cant locate it on the web!

the best place to start is the MapReduce paper by Jeff Dean ...and try
googling a talk by google's Aron on MapReduce
