grahical tool for hadoop mapreduce

[Manhee Jo]

Hi,

Do you know any graphical tools to show the progress of mapreduce using
the job log under logs/history/ ? The web interface (namenode:50030) gives 
me
similar one. But what I need is more specific ones that show the number of
total running map tasks and reduce tasks at some points of time,
which I've seen from some papers. Any help would be appreciated.

Thanks,
Manhee
