Jing Zhao commented on HDFS-8483:
---------------------------------

Yeah, actually we can add more tests in HDFS-8619 to verify datanode reporting bad blocks.
Currently it only covers client side report. [~tasanuma0829], please see if you want to add
the test here or you want me to add the test in HDFS-8619.

> We can mimic one/several DataNode(s) reporting bad block(s) (which belong to a striped
block) to the NameNode (through the DatanodeProtocol#reportBadBlocks call), and check if the
recovery/invalidation work can be correctly scheduled.
