    Description

      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.
