stack commented on HBASE-48:
----------------------------
Yes. Going behind the API would be the faster way to load hbase. It'd be
dangerous to do into a live hbase. Should we write something like
TableOutputFormatter except it writes region files directly into hdfs? It'd
make a region per reducer instance? It'd know how to write keys, etc. properly
and what location in hdfs to place files.
> [hbase] Bulk load and dump tools
> --------------------------------
>
> Key: HBASE-48
> URL: https://issues.apache.org/jira/browse/HBASE-48
> Project: Hadoop HBase
> Issue Type: New Feature
> Reporter: stack
> Priority: Minor
>
> 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.
