-------------------------------------
Hey [~busbey]
the current tests will test that everything still works the same with the
rename added.
It don't however test that a rename happened.
> Spark Bulk Load: Need to write HFiles to tmp location then rename to protect
> from Spark Executor Failures

> With the current code if an executor failure before the HFile is close it
> will cause problems. This jira will have the files first write out to a file
> that starts with an underscore. Then when the HFile is complete it will be
> renamed and the underscore will be removed.
> The underscore is important because the load bulk functionality will skip
> files with an underscore.
