> HADOOP:5937 changes the safemode usage message from "hadoop dfs -safemode leave" to turn safe mode off to "hdfs dfsadmin -safemode leave" to turn safe mode off. But bin/hdfs is supported only in 21 (after the project split) and not on branch 20. Hence this patch introduces a new bug and should not be applied to 20 branch. 
> Instead, the patch should be modified for branch 20 to read the usage message as "hadoop dfsadmin -safemode leave" to turn safe mode off.
