Konstantin Shvachko commented on HDFS-3598:
-------------------------------------------
I think we should add concat() to FileSystem API and make it available through
WebHDFS.
FileSystem has plenty of methods custom to HDFS only starting with
getFileBlockLocations().
WebHDFS allows concurrent load of files because it redirects to individual
DataNodes.
With concat() one will be able to efficiently load large files via http.
> WebHDFS: support file concat
