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.
{quuote}
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
{quote}
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.
