Hairong Kuang commented on HADOOP-2652:
---------------------------------------

The patch looks good to me. It would be nicer if the replication monitor can 
adjust its frequency dynamically. It slows itself down when the namenode 
becomes busy and replicates more aggressively when the namenode becomes idle.
