Permission checking in fsck
---------------------------
Key: HADOOP-4268
URL: https://issues.apache.org/jira/browse/HADOOP-4268
Project: Hadoop Core
Issue Type: New Feature
Components: dfs
Affects Versions: 0.17.2
Reporter: Koji Noguchi
Quoting from HADOOP-3222 ("fsck should require superuser privilege"),
bq. I agree that it makes sense to make fsck do permission checking for the
nodes that it traverses. If a user does a fsck on files/directories that he/she
has access to (using permissions) then that invocation of fsck should be
allowed. Since "/" is usually owned by super-user, only super-user should be
allowed to run fsck on "/".
