Konstantin Shvachko commented on HDFS-708:
------------------------------------------
Hi Wang Xu. Thanks for the link. I think people will find your scripting
solution useful for testing HDFS directly without the MapReduce framework.
What we want to achieve by this is to model the workload of a real cluster and
test it on that load. MR is a part of testing for us.

> It would be good to have a tool for automatic stress testing HDFS, which
> would provide IO-intensive load on HDFS cluster.
> The idea is to start the tool, let it run overnight, and then be able to
> analyze possible failures.
