Subject [jira] [Commented] (HADOOP-9929) Insufficient permissions for a path reported as file not found
Date Wed, 18 Sep 2013 21:01:53 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13771234#comment-13771234

Colin Patrick McCabe commented on HADOOP-9929:
----------------------------------------------

Andre, I tried to reproduce this on branch-2.1-beta, and was unable to do so.

{code}
cmccabe@keter:~/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -ls /
cmccabe@keter:~/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -mkdir /a
cmccabe@keter:~/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -chmod 0000 /a
cmccabe@keter:~/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -mkdir /a/b
su other
d---------   - cmccabe supergroup          0 2013-09-18 13:57 hdfs://localhost:6000/a
other@keter:/home/cmccabe/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -ls hdfs://localhost:6000/a/b
ls: Permission denied: user=other, access=EXECUTE, inode="/a":cmccabe:supergroup:d---------
other@keter:/home/cmccabe/hadoopST/branch-2.1-beta> /h/bin/hadoop fs -ls hdfs://localhost:6000/*/b
ls: Permission denied: user=other, access=EXECUTE, inode="/a":cmccabe:supergroup:d---------
{code}

I also looked at the code in branch-2.1-beta, and was unable to see why this bug would exist
there.  So I would like to remove branch-2.1-beta from the versions fields, unless someone
else can reproduce this.

> Using "hadoop fs -ls" to list a path where the permissions of a parent directory are
insufficient ends up reporting "no such file or directory" on the full path rather than reporting
the permission issue.  For example:
> {noformat}
> $ hadoop fs -ls /user/abc/tests/data
> ls: `/user/abc/tests/data': No such file or directory
> $ hadoop fs -ls /user/abc
> ls: Permission denied: user=somebody, access=READ_EXECUTE, inode="/user/abc":abc:hdfs:drwx------
> {noformat}
