Steve Loughran commented on HADOOP-9454:
----------------------------------------
core changes look good, and this upgrades to the latest jets3t, superceding
HADOOP-8136.
What it lacks is any test of multipart upload.
I would recommend lifting
[[https://github.com/hortonworks/Hadoop-and-Swift-integration/blob/converged/swift-file-system/src/test/java/org/apache/hadoop/fs/swift/TestSwiftFileSystemPartitionedUploads.java]]
and using it as the basis for a test. It probes the output stream for the
number of parts uploaded, and verifies that the result of the bulk upload
matches the original
> 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.
