> I tested the  tez example OrderedWordCount on my cluster.My input file more than 200MB,and it will generate 4 tasks.But I found this 4 tasks all run on one node which is different everytime.My cluster contains one master and two slaves.My idea is this task should be run on different node,for example,there are two  Tokenizer tasks should be run on two different nodes.this can show the distribution on the cluster.I don't know how to explain this phenomenon.and I guess if need to modify some configuration or set some information to realize my imaginative distribution. Who can explain why or tell me if need some configuration.Thank you very much
