That's right, it should be noted however that the need of horizontally scaling the equivalent of the NameNode kicks in only when you really have a very large storage system, where large can be defined as: "You know you have a large storage
system when you get paged at 1 AM because you only have a
few petabytes of storage left." [1] Even if you are below that size you might have a large system, and even if using a single metadata master node might be a sound solution you still have lot of interesting problems to solve. Don't make systems more complex than necessary. More pointers to google public material on colossus in [2]. [1] http://static.googleusercontent.com/media/research.google.co...
