Subject [jira] [Commented] (HADOOP-10965) Incorrect error message by fs -copyFromLocal
Date Tue, 22 Mar 2016 20:58:25 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15207286#comment-15207286

Andrew Wang commented on HADOOP-10965:
--------------------------------------

So the issue is not homedir specific, it relates to the CWD (current working directory), which
by default happens to be the homedir.

As I suggested above, why not just add the fully qualified path to the error message? The
path could be missing on either the local FS or in HDFS, and showing the fully qualified path
would address both cases without ambiguity.

> Whenever I try to copy data from local to a cluster, but forget to create the parent
directory first, I get a very confusing error message:
> {code}
> $ whoami
> fs111
> $ hadoop fs -ls  /user
> Found 2 items
> drwxr-xr-x   - fs111   supergroup          0 2014-08-11 20:17 /user/hive
> drwxr-xr-x   - vagrant supergroup          0 2014-08-11 19:15 /user/vagrant
> $ hadoop fs -copyFromLocal data data
> copyFromLocal: `data': No such file or directory
> {code}
> From the error message, you would say that the local "data" directory is not existing,
but that is not the case. What is missing is the "/user/fs111" directory on HDFS. After I
created it, the copyFromLocal command works fine.
> I believe the error message is confusing and should at least be fixed. What would be
even better, if hadoop could restore the old behaviour in 1.x, where copyFromLocal would just
create the directories, if they are missing.
