Yes, that's correct. I've never tried bulk loading from S3 on 2.x

Thanks for the info, Austin. I'm guessing that's how 1.x works since
you mention EMR?
I think this code has changed in 2.x with the SecureBulkLoad stuff
moving into "core" (instead of external as a coproc endpoint).

Sorry for the late reply. You should be able to bulk load files from
S3 as it will detect that they're not the same filesystem and have
the regionservers copy the files locally and then up to HDFS. This is
related to a problem I reported a while ago when using HBase on S3
with EMR.

Ah yeah, didn't realise it would assume same FS, internally. Indeed,
no way
to have rename working between different FSes.

Short answer: no, it will not work and you need to copy it to HDFS
first.
IIRC, the bulk load code is ultimately calling a filesystem rename
from
the path you provided to the proper location in the hbase.rootdir's
filesystem. I don't believe that an `fs.rename` is going to work
across
filesystems because you can't do this atomically, which HDFS
guarantees
for the rename method [1]
Additionally, for Kerberos-secured clusters, the server-side bulk load
logic expects that the filesystem hosting your hfiles is HDFS (in
order
to read the files with the appropriate authentication). This fails
right
now, but is something our PeterS is looking at.

I believe you can specify your s3 path for the hfiles directly, as

FileSystem does support s3a scheme, but you would need to add your s3
access and secret key to your completebulkload configuration.

If I have Hfiles stored in S3, can I run CompleteBulkLoad and
provide an
S3 Endpoint to run a single command, or do I need to first copy
the S3
Hfiles to HDFS first? The documentation is not very clear.
