Jakob Homan commented on HADOOP-5358:
-------------------------------------

Neither of the failed tests are related to my patch.  One is a time-out, the other a Chukwa
issue.

> Currently the load generator accepts parameters at start time as to the read and write
probabilities to apply against the namenode.  It would be useful to be able to provide it
with a script of these values, so that they can be varied over time.  This would allow the
namenode to be tested with varying loads over time so its behavior to changing loads can be
examined.
