> When the 2NN or BN needs to sync up with the primary NN, it may need to
> download several different edits files since the NN may roll whenever it
> likes. This JIRA adds a new type called RemoteEditLogManifest to list the
> available edit log files since a given transaction ID. This may also be
> useful for monitoring or backup tools down the road.
