Some Storage communication related questions

[Wasim Bari]

Hi,
     I have multiple questions:

Does hadoop use some parallel technique for CopyFromLocal and CopyToLocal  
(like DistCp) Or its simple ONE stream writing?

For Amazon S3 to Local system communication, Hadoop uses Rest service interface 
or SOAP ?

Are there some new storage systems currently in pipeline to be interfaced with 
hadoop ?


Thanks,

Wasim
