Konstantin Shvachko commented on HDFS-1286:
-------------------------------------------
Interesting catch. We should ask somebody to look at Hudson machines.
On the other hand we should also avoid using random data in tests. Tests should
be reproducible by definition. Using random bytes does not achieve this goal.
So replacing random with sequential sounds like the right direction to me.
