stack updated HBASE-48:
-----------------------
Attachment: 48-v4.patch
This patch seems to basically work. I took files made by the
TestHFileInputFormat test and passed them to the script as follows:
{code}
$ ./bin/hbase org.jruby.Main bin/loadtable.rb xyz /tmp/testWritingPEData/
{code}
The script expects hbase to be running.
It ran through the list of hfiles, read their meta info and last key. It then
sorted the hfiles by end key. It makes a HTableDescriptor and
HColumnDescriptor with defaults (If want other than defaults, then after
upload, alter table). It then takes the sorted files and per file moves it
into place and adds a row to .META. Doesn't take long.
The meta scanner runs after the upload and deploys the regions.
Done.
I'll not work on this anymore, not till someone else wants to try it.
> [hbase] Bulk load and dump tools

> 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.
