      Description

      Playing with trunk, I managed to get a DataNode in a situation where the BlockPoolSliceScanner is spinning in the following loop, using 100% CPU:
      at org.apache.hadoop.hdfs.server.datanode.DataNode$BPOfferService.isAlive(DataNode.java:820)
      at org.apache.hadoop.hdfs.server.datanode.DataNode.isBPServiceAlive(DataNode.java:2962)
      at org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner.scan(BlockPoolSliceScanner.java:625)
      at org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner.scanBlockPoolSlice(BlockPoolSliceScanner.java:614)
      at org.apache.hadoop.hdfs.server.datanode.DataBlockScanner.run(DataBlockScanner.java:95)
