John Zhuge updated HADOOP-10965:
Attachment: HADOOP-10965.002.patch
Patch 002:
* Fix FS shell command copy and touchz to print the fully qualified path in
the error message when the path can not be found. It will show the current
directory and file system which can help users take proper corrective actions.
Test output:
{code}
$ hdfs dfs -touchz f1
touchz: `f1': No such file or directory: `hdfs://nnhost:8020/user/systest/f1'
$ hdfs dfs -put d1 d1
put: `d1': No such file or directory: `hdfs://nnhost:8020/user/systest/d1'
{code}

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/'; 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}
