> HDFS-4274 fixed a file handle leak of the block scanner's verification logs
> by adding method {{BlockPoolSliceScanner#shutdown}} and guaranteeing that the
> method gets called for each live {{BlockPoolSliceScanner}} during datanode
> shutdown. However, that patch did not consider the case of deleting a block
> pool via {{ClientDatanodeProtocol#deleteBlockPool}} while the datanode
> remains running.
