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 allows copy even if directory permissions are 000.
