Description

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.
