-------------------------------------
Summary: HDFS user permission does not work correctly
Key: HDFS-15615
URL: https://issues.apache.org/jira/browse/HDFS-15615
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Heba Aboulmagd
HDFS users can create/delete folders for each other, while the permission is
set to {{745}} on {{/user/username}}.
I used the following commands to create users and set their permissions
{{useradd -m -g hdfs username}}
{{su hdfs}}
{{hdfs dfs -mkdir -p /user/username}}
{{hdfs dfs -chown username:hdfs /user/username}}
{{hdfs dfs -chmod 745 /user/username}}
when {{user1}} executes: {{hdfs dfs -mkdir /user/user2/from_user1}}
{{The directory is created successfully}}
The same happens when {{user1}} tries to delete files from {{/user/user2}}
while the permission is set to read only for the users in the same group.g
