DFS shell get/copy gives weird errors when permissions are wrong with
directories
---------------------------------------------------------------------------------
Key: HADOOP-7943
URL: https://issues.apache.org/jira/browse/HADOOP-7943
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.20.205.0
Reporter: Ben West
Priority: Minor
Let /foo be a *directory* in HDFS (issue does not occur with files) and /bar be
a local dir. Do something like:
{code}
$ chmod u-w /bar
$ hadoop -get /foo/myfile /bar
copyToLocal: Permission denied # correctly tells me permission is denied
$ hadoop -get /foo /bar
copyToLocal: null
$ hadoop -get /foo/ /bar
copyToLocal: No such file or directory
{code}
I've been banging my head for a bit trying to figure out why hadoop thinks my
directory doesn't exist, but it turns out the problem was just with my local
permissions. The "Permission denied" error would've been a lot nicer to get.
