You want to store a 500 MB file into a cluster with 12 nodes, which are located in four different racks (three nodes per rack) as shown in the figure below.
- If a data block can store 128 MB, how many data blocks are needed to split this file?
- Use a replication factor of 3 and the write principles discussed earlier to allocate the data blocks into this cluster.
- Repeat steps 1 and 2 but with a block size of 256 MB.
