> In the JobTracker webui, for successful jobs, I sometimes see inconsistency
> in the count of the number of various task types whenever some speculative
> tasks (esp. maps) are executed. So for example, if the job has 1000 maps, I'd
> expect that on a successful job run, the count of the number of pending map
> tasks to be 0. But sometimes, when there are speculative tasks, the pending
> count is greater than 0, and the completed tasks count is less than the
> number of the total tasks that the job originally had.
