Subject [jira] [Created] (HADOOP-9006) Winutils should keep Administrators privileges intact
Date Fri, 02 Nov 2012 22:44:13 GMT
Chuan Liu created HADOOP-9006:

             Summary: Winutils should keep Administrators privileges intact
                 Key: HADOOP-9006
                 URL: https://issues.apache.org/jira/browse/HADOOP-9006
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Chuan Liu
            Priority: Minor

This issue was originally discovered by [~ivanmi]. Cite his words as follows.

Current by design behavior is for winutils to ACL the folders only for the user passed in
thru chmod/chown. This causes some un-natural side effects in cases where Hadoop services
run in the context of a non-admin user. For example, Administrators on the box will no longer
be able to:
 - delete files created in the context of Hadoop services (other users)
 - check the size of the folder where HDFS blocks are stored

In my opinion, it is natural for some special accounts on Windows to be able to access all
the folders, including Hadoop folders. This is similar to Linux in the way root users on Linux
can always access any directories regardless the permissions set the those directories.
