Subject [jira] Commented: (HADOOP-672) dfs shell enhancements
Date Fri, 16 Mar 2007 21:23:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12481767
] 

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.
