> HFileOutputFormat.configureIncrementalLoad is not setting all the io
> serializations correctly so custom bulk loaders (like ImportTsv) need to set
> it. Simple fix, just add what's missing.
> In case someone doesn't get this patch but upgrades to an old RC, this is
> what you'll see when running via YARN (or similar if MR1):
