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.
