@hfutatzhanghb Hi, bro thanks for your comment.
yeah, modification is similar to what method BlockManager#removeBlock does.
If the block is no included in the BlocksMap, when DN processed invalidating
blocks , should not need to notify the Namenode.
I will add UT try to illustrate this case.
> Process reported block toInvalidate logic should set the block size to NO_ACK
