             Summary: Shouldn't start block recovery if block has no enough replicas
                 Key: HDFS-9232

from HDFS-8406:

Before primary DN calls commitBlockSynchronization, it synchronized 2 RBW replicas, and make
them finalized. Then primary DN calls commitBlockSynchronization, to complete the lastBlock
and close the file. The question is, your dfs.namenode.replication.min is 3, the last block
can't be completed. NameNode shouldn't issue blockRecovery in the first place because lastBlock
can't be completed anyway.
