Description

Routers may be proxying for a downstream name node that is NOT migrated to understand "ProvidedCapacityTotal". updateJMXParameters method in NamenodeHeartbeatService should handle this without breaking.

 

                jsonObject.getLong("MissingBlocks"),
                jsonObject.getLong("PendingReplicationBlocks"),
                jsonObject.getLong("UnderReplicatedBlocks"),
                jsonObject.getLong("PendingDeletionBlocks"),
                jsonObject.getLong("ProvidedCapacityTotal"));

One way to do this is create a json wrapper while gives back some default if json node is not found.
