> TransferFsImage#doGetUrl downloads files from the specified url and stores
> them in the specified storage location. HDFS-4025 plans to synchronize the
> log segments in JournalNodes. If a log segment is missing from a JN, the JN
> downloads it from another JN which has the required log segment. We need
> TransferFsImage#doGetUrl and TransferFsImage#receiveFile to accomplish this.
> So we propose to move the said functions to a Utility class so as to be able
> to use it for JournalNode syncing as well, without duplication of code.
