stack updated HBASE-48:
-----------------------

    Summary: [hbase] Bulk load tools  (was: [hbase] Bulk load and dump tools)

I deleted my last comment.  It was duplication of stuff said earlier in this issue a good while ago.

I changed title of this issue to only be about bulk upload.   The bulk dump is going on elsewhere: e.g. HBASE-1684

On earlier comments about splitting table so at least a region per regionserver, that ain't hard to do now.  You can do it via UI -- force a split -- or just write a little script to add a table and initial region range (for example, see the script in the attached patch).

I think criteria for closing this issue is commit of some set of tools that allow writing hfiles either into new tables or into extant tables.

> 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.
