-Re: How to run data node block scanner on data node in a cluster from a remote machine?
No there isn't a programmatic way to invoke the block scanner. Note
though that the property to control its period is DN-local, so you can
change it on DNs and do a DN rolling restart to make it take effect
without requiring a HDFS downtime.
