From "Tsz Wo (Nicholas), SZE (JIRA)" <j...@apache.org>
Subject [jira] Commented: (HADOOP-3913) Distcp allows copy even if directory permissions are 000.
Date Wed, 13 Aug 2008 20:22:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12622340#action_12622340
] 

Tsz Wo (Nicholas), SZE commented on HADOOP-3913:
------------------------------------------------

I tried the following
# Login as tsz
## created a 0.17 cluster 
## created a 0.18 cluster
## created home directory for "sze" in both cluster
# Login as sze (a non-superuser for both clusters)
## mkdir and copied some files to /user/sze/foo in the 0.18 cluster
## distcp the files in /user/sze/foo from the 0.18 cluster to the 0.17 cluster (success)
## chmod 000 /user/sze/foo in the 0.18 cluster
## distcp the files in /user/sze/foo from the 0.18 cluster to the 0.17 cluster (failed with
the same error message shown in HADOOP-3889)

So, I cannot reproduce it.  Could you check it, Suman?

> distcp initiated from 0.17.0 and 0.18.0 permissions turned ON, directory with permission
000, data gets copied from
> 0.18.0 to 0.17.0 
> Data gets copied between different versions of hadoop when tried by the same user. It
gets failed only if other
> user(other than the user who started cluster) tries to copy data using distcp.
