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

[~ayushtkn]

-HDFS-9023 defines BlockPlacementPolicy.LOG.debug instead of LOG.debug. i think 
LOG.debug is more reasonable.  Unified definition of log mode. Please correct 
me if was wrong. Thank you a lot [~ayushtkn]

> There is a noisy log with BlockPlacementPolicy.LOG, it's too hard to debug 
> problem. Define LOG instead of it in DatanodeDescriptor#chooseStorage4Block.
