> Currently in the HDFS-1073 branch, the code for creating output streams is in FileJournalManager
and the code for input streams is in the inspectors. This change does a number of things.
>   - Input and Output streams are now created by the JournalManager.
>   - FSImageStorageInspectors now deals with URIs when referring to edit logs
>   - Recovery of inprogress logs is performed by counting the number of transactions instead
of looking at the length of the file.
> The patch for this applies on top of the HDFS-1073 branch + HDFS-2003 patch.
