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.
