Subject [jira] [Commented] (HADOOP-10965) Incorrect error message by fs -copyFromLocal
Date Thu, 04 Feb 2016 19:43:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15132869#comment-15132869

John Zhuge commented on HADOOP-10965:
-------------------------------------

[~andrew.wang], do see your point of printing the same path in error message as input. BTW,
the absolute paths often expand to long strings which clutter the console a little bit.

> 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.
