> We need to update the safemode calculation for striped blocks. Specifically, each striped
block now consists of multiple data/parity blocks stored in corresponding DataNodes. The current
code's calculation is thus inconsistent: each striped block is only counted as 1 expected
block, while each of its member block may increase the number of received blocks by 1.
