> In the HBaseTest load test we have a condition when the writer has not
> written any keys but the reader might attempt to read key 0, resulting in a
> failure. This bug is specific to 89-fb because it has been fixed while
> open-sourcing HBaseTest as LoadTestTool, and those improvements still have
> not been back-ported to 89-fb. Doing a temporary fix now and we will get to
> the back-port later.
