Hey everyone, I have a situation where case sensitivity of principals is causing some pains. Here's the set up
AD Centrify (Centrify.com) hadoop on RHEL The logins to the cluster are all using LDAP/PAM . When I do something like "id" then it returns the lowercase version of the user. "env" return the upper case version for example id uid=1234(user1234) env | grep USER_PRIN USER_PRINCIPAL_NAME=USER1234@REALM When the user1234 tries to write to hdfs with a home directory of /user/user1234 I receive a permission error. If I create it as /user/USER1234 then it behaves correctly. If I were to just push a file to HDFS /tmp it looks like -rw-r--r-- 3 USER1234 hdfs 1234 2005-03-07 15:34 /tmp/file To make matters a little more complicated some usernames are mixed case so either upper or lower is not sufficient. I just want to force to a lower case user. So, my question is this: Is there a way to tell the kerberos setup in HDFS to force lowercase users (matching what linux does) so that the admins do not go crazy figuring out silly things like case? Thanks in advance.
