    Description

      DistributedFileSystem.create allows to get a FSDataOutputStream. The stored file and related blocks will used the directory based StoragePolicy.

       

      However, sometime, we might need to keep all files in the same directory (consistency constraint) but might want some of them on SSD (small, in my case) until they are processed and merger/removed. Then they will go on the default policy.

       

      When creating a file, it will be useful to have an option to specify a different StoragePolicy...
