> The test fails because of a race condition between the test and the
> replication monitor. The default replication monitor interval is 3 seconds,
> which is just about how long the test normally takes to run. The test deletes
> a file and then subsequently gets the namesystem writelock. However, if the
> replication monitor fires in between those two instructions, the test will
> fail as it will itself invalidate one of the blocks. This can be easily
> reproduced by removing the sleep() in the ReplicationMonitor's run() method
> in BlockManager.java, so that the replication monitor executes as quickly as
> possible and exacerbates the race.
> To fix the test all that needs to be done is to turn off the replication
> monitor.
