Philip Zeyliger commented on HDFS-1547: --------------------------------------- Hi Suresh, For decomissioning, it's always seemed a bit odd that interacting with the system requires editing a file local to the namenode as well as sending an RPC. Have you considered adding RPCs (and CLI wrappers for them) for explicitly updating data node states, without going through a file?
