-----------------------------------------

bq. It would be nice if the Hadoop guys used jclouds instead of their 
home-grown implementations...

interesting point. FWIW, I'd be happy with a generic jclouds client which can 
bind with anything.

But bear in mind we are trying to do some fairly low-level ops for (a) 
performance and (b) commit protocols, while also handling sources and dest 
files which can be measured in tens, to hundreds of GB. For S3 and the Azure 
stores we use the vendor SDKs, the leasing calls in Azure for atomic renames, 
and consistent view over S3 coming in HADOOP-13345. The seek optimisations 
force us to make decisions in the S3 client when to abort a TCP stream vs 
read-and-discard to end of stream, we have different content-length header 
policies optimised for column formats like ORC and Parquet (HADOOP-13203)

So: a jcloud client would be good, happy to pull in. Not going to move off our 
s3a, azure wasb or adl clients tho'
