Hi,
I have a 10 nodes Hadoop cluster, where I am running some benchmarks for
experiments.
Surprisingly, when I initialize the Hadoop cluster
(hadoop/bin/start-mapred.sh), in many instances, only some nodes have
TaskTracker process up (seen using jps), while other nodes do not have
TaskTrackers. Could anyone please explain?
