Subject [jira] [Commented] (HADOOP-8074) Small bug in hadoop error message for unknown commands
Date Thu, 16 Feb 2012 16:34:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209481#comment-13209481

Daryn Sharp commented on HADOOP-8074:

Levenstein is a very cool idea for suggesting alternatives!  Apache Common's StringUtils even
has a method for it.  It's a handful of lines to implement, so I can post a patch with it
later today if you can please help me out with updating the hdfs tests since I've got more
demanding priorities...

the command. Also, this should say "cat" rather than "at".
