Tom White commented on HADOOP-8545:
-----------------------------------
I'm not sure whether the blockstore implementation is the right approach. The
main drawback is that it's a Hadoop-specific format, which other tools can't
read, and which will introduce a support burden. The S3 blockstore was
introduced when there was a limit on the size of files, which has since been
removed, so if I was doing it today I would probably not have a S3 blockstore
implementation. I would encourage you to look at more general support for large
files in Swift, e.g.
http://docs.openstack.org/developer/swift/overview_large_objects.html.
