Arpit Agarwal commented on HDFS-8687:
-------------------------------------
Hi [~brahmareddy], thanks for submitting this fix.
We should remove the line {{ToolRunner.printGenericCommandUsage(System.err);}}
instead. Looks like removing printUsage will only print the generic options.
> Remove the duplicate usage message from Dfsck.java
