How to run data node block scanner on data node in a cluster from a remote machine?


By default data node executes block scanner in 504 hours. This is the
 default value of dfs.datanode.scan.period . If I want to run the data 
node block scanner then  one way is to configure the property of 
dfs.datanode.scan.period in hdfs-site.xml but is there any other other 
way.
 Is it possible to run data node block scanner on data node either 
through command or pragmatically.
