Konstantin Shvachko updated HDFS-708:
-------------------------------------

    Attachment: SLiveTest.pdf

Updating the design doc. Section "Data Generation and Verification" has been updated. The
old design turned out to be incompatible with file renames. Now it is compatible with renames,
but files have to be read from the beginning.

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.
