> Hbase needs tools to facilitate bulk upload and possibly dumping.  Going via the current
APIs, particularly if the dataset is large and cell content is small, uploads can take a long
time even when using many concurrent clients.
> PNUTS folks talked of need for a different API to manage bulk upload/dump.
> Another notion would be to somehow have the bulk loader tools somehow write regions directly
in hdfs.
