Subject [jira] [Commented] (HADOOP-9454) Support multipart uploads for s3native
Date Thu, 04 Apr 2013 09:13:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13621952#comment-13621952

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

> 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.
