[jira] [Created] (HADOOP-8074) Small bug in hadoop error message
for unknown commands
Small bug in hadoop error message for unknown commands
------------------------------------------------------
Key: HADOOP-8074
URL: https://issues.apache.org/jira/browse/HADOOP-8074
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 0.24.0
Reporter: Eli Collins
Assignee: Colin Patrick McCabe
Priority: Trivial
Fix For: 0.23.2
The hadoop fs command should be more user friendly if the user forgets the dash before the command. Also, this should say "cat" rather than "at".
{noformat}
hadoop-0.24.0-SNAPSHOT $ ./bin/hadoop fs cat
at: Unknown command
{noformat}

Or for user-friendliness, something like this. I was hoping someday to make the leading dash optional if I got around to adding interactive readline support.

-------------------------------------
I guess my request to review got overlooked. FsShell is not designed to enforce a leading dash, it's actually completely generic and it just happens that commands today start with a dash. The more correct patch would have been:

Eli Collins commented on HADOOP-8074:
-------------------------------------
Hey Daryn,
Sorry, missed your comment in the stream of comments! Mind filing a jira for your suggested improvement? I'd be happy to review / commit.
Also, how about filing a jira for your idea of making the leading dash optional? It's currently not optional in FsShell (all hadoop commands must have form <cmd> <-cmd>) which is why I think the current change is reasonable.
Thanks,
Eli

-------------------------------------
Forgot to mention, Colin tried to add a test but ran into HADOOP-7360 / HDFS-2038, I'll ping those jiras. We'll test the output of TestHDFSCLI w/ and w/o this change for sanity. Given that it only updates the error handling path it shouldn't have an impact.

[jira] [Commented] (HADOOP-8074) Small bug in hadoop error message
for unknown commands
Posted by "Colin Patrick McCabe (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-8074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209043#comment-13209043 ]
Colin Patrick McCabe commented on HADOOP-8074:
----------------------------------------------
Hi Daryn,
I like your idea of accepting the commands without a leading dash. It makes sense to me.
Another improvement we could consider is enhancing FsShell to do a more general "did you mean" type search. You could point out the one or two commands with the shortest Levenstein distance from what the user entered.
For now, this change catches the fairly common case where a first-time user types the command without a dash, and then is mystified when it doesn't work. I know that this can happen because I was that first-time user at one point!
Colin

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...

Agree. Let's knock out your (Daryn's) suggested improvements and at least file a jira for accepting commands without a leading dash as well.
