---------------------------------
Besides, you can also create a separate jira to add more unit tests to address
the TODO in TestSafeMode.java.

> 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.
