Let's say my replication factor is 3. Let's assume I want to write block b of some file f to nodes A, B and C. For whatever reason let's assume that write to C fails completely. So the write is a success only at A and B. How is this block re-replicated on to a 3rd node? I am assuming that it happens during some container report but how? Are all blocks that make up a container part of the report i.e does a report for container C report all blocks in the container?
