Madhu,

That is incorrect. TestDFSIO is a MapReduce job and you need HDFS+MR
setup to use it.

DFSIO

2011-11-24 Thread Thanh Do 
hi all,

in order to run DFSIO in my cluster,
do i need to run JobTracker, and TaskTracker,
or just running HDFS is enough?

Many thanks,
Thanh

DFSIO benchmark

2011-03-31 Thread Matthew John 
Can some one provide pointers/ links for DFSio Benchmarks to check the IO
performance of HDFS ??

Thanks,
Matthew John
