Kai Zheng commented on HDFS-9733:
---------------------------------

Having checked the test failures and they're passed locally as not related to 
this.
The refactoring strictly follows the current behavior and existing tests can 
ensure that. Will add more tests along with striped file checksum computing.

> Refactor DFSClient#getFileChecksum and DataXceiver#blockChecksum
