Copy file using Webhdfs

[Stuti Awasthi <st...@hcl.com>]

Hi ,
I am using webhdfs (REST urls) in hadoop-1.0.0 for filesystem operation. I am following "http://hadoop.apache.org/common/docs/r1.0.0/webhdfs.html "
There is no url supported for Copy files with HDFS. Usually we do it with FileUtils api or "-cp" command of shell.
Do we have a way to copy files in webhdfs also ?

Thanks
Stuti

Copying files has always involved downloading the data and then uploading it again. This is true of both FileUtils, and -cp from the command line.  IT really would be great to have a way for HDFS to do it for you, behind the scenes, but that is not implemented yet.
