Jonathan Gray updated HBASE-48:
-------------------------------

    Attachment: HBASE-48-v6-branch.patch

Patch that applies cleanly to branch.

Includes two modifications to the ruby script.  Ignores _log directories (preventing multiple-family error) and copies hfiles into proper region directories, after creating them.

Running final test now.

> 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.
