    Description

      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.
