--------------------------------------------------------------
[~liuguanghua] Maybe I didn't describe it clearly, the above processing is in
the namenode, and does not need to be processed in the datanode end. The FBR
is to align the block information of the namenode and datanode history. Now we
can determine that FBR blocks in the DN have been added to the namenode by IBR,
but we cannot guarantee that all the added blocks by IBR are included in FBR
this time, right？
for 3.3.0 ，Just delete the red box code
