Raghu Angadi commented on HADOOP-672:
-------------------------------------
1) Looks like this will print help for all commands if I say '-help unknown'.
Is that intentional?
2)
+ } else if ("-help".equals(cmd)) {
+ System.err.println("Usage: java FsShell" +
+ " [-help [cmd]]");
+
This is never excuted, both in FS and DFS, I think because there is no wrong
way to invoke -help command.
