> 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.
