Joshua Harlow updated HDFS-708:
-------------------------------
Attachment: slive.patch
Updated with in file "header" like information so that when a file is renamed
the "header" information can still be used to do basic data verification. Tried
this out and it seems to work. Also updated so that file not found exceptions
are reported different and added a bad file exception which signifies a data
read failure (ie a header can not be read or is invalid) or an end of file
happend when it should not.
> A stress-test tool for HDFS.

> 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.
