> This jira proposes to record the replication factor in the {{BlockInfo}}
> class. The changes have two advantages:
> * Decoupling the namespace and the block management layer. It is a
> prerequisite step to move block management off the heap or to a separate
> process.
> * Increased flexibility on replicating blocks. Currently the replication
> factors of all blocks have to be the same. The replication factors of these
> blocks are equal to the highest replication factor across all snapshots. The
> changes will allow blocks in a file to have different replication factor,
> potentially saving some space.
