Jordan Mendelson commented on HADOOP-9454:
------------------------------------------
I doubt we're going to get those warnings down without a more major overhaul.
They are due to the fact that many of the interfaces used in both the s3 and
s3native filesystems were deprecated in 0.8.0. They still work, but they should
be swapped out for the newer more generic interface.
> Support multipart uploads for s3native

> The s3native filesystem is limited to 5 GB file uploads to S3, however the
> newest version of jets3t supports multipart uploads to allow storing multi-TB
> files. While the s3 filesystem lets you bypass this restriction by uploading
> blocks, it is necessary for us to output our data into Amazon's
> publicdatasets bucket which is shared with others.
> Amazon has added a similar feature to their distribution of hadoop as has
> MapR.
