----------------------------------

Ok. Thanks Nicholas for confirmation. I agree it shouldn't be a bug but intentional.
+1 on the new patch.

> In HDFS-4990, the block placement target type was changed from DatanodeDescriptor to
DatanodeStorageInfo.  The block schedule information, such as the number of blocks scheduled
for replication (i.e. getBlocksScheduled()), should be moved from DatanodeDescriptor to DatanodeStorageInfo.
