John Zhuge updated HADOOP-10965:
--------------------------------
Status: In Progress (was: Patch Available)
[~andrew.wang] and [~yzhangal], the most common and perplexing mistake a new
HDFS user can make is having forgot to create the home directory. It could even
take a seasoned user a little while to realize the mistake. How about
triggering a new {{HomeDirectoryNotFoundException}} when accessing a relative
path and home directory having not been created? The exception should print the
home directory path for 2 reasons: 1) Some user may not know the format
'/user/<name>'; 2) The admin might have changed the home directory path
template (very unlikely though).
For example:
{code}
$ fs -put f1 f1
put: f1: Home directory '/user/jack' not found
{code}
> Incorrect error message by fs -copyFromLocal

> 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.
