Description

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.
