Stephen Chu created HDFS-4913:
---------------------------------
Summary: Deleting file through fuse-dfs when using trash fails
requiring root permissions
Key: HDFS-4913
URL: https://issues.apache.org/jira/browse/HDFS-4913
Project: Hadoop HDFS
Issue Type: Bug
Components: fuse-dfs
Affects Versions: 2.0.3-alpha
Reporter: Stephen Chu
As _root_, I mounted HDFS with fuse-dfs using the -ousetrash option.
As _testuser_, I cd into the mount and touch a test file at
_/user/testuser/testFile1_. As the same user, I try to rm the file and run into
an error:
{code}
[testuser@hdfs-vanilla-1 ~]$ cd /hdfs_mnt/user/testuser
[testuser@hdfs-vanilla-1 testuser]$ touch testFile1
[testuser@hdfs-vanilla-1 testuser]$ rm testFile1
rm: cannot remove `testFile1': Unknown error 255
{code}
I check the fuse-dfs debug output, and it shows that we attempt to mkdir
/user/root/.Trash, which testuser doesn't have permissions to.
Ideally, we'd be able to remove testFile1 and have testFile1 be put into
/user/testuser/.Trash instead of /user/root/.Trash.
Error in debug:
{code}
unlink /user/testuser/testFile1
hdfsCreateDirectory(/user/root/.Trash/Current/user/testuser): FileSystem#mkdirs
error:
org.apache.hadoop.security.AccessControlException: Permission denied:
user=testuser, access=WRITE, inode="/user/root":root:supergroup:drwxr-xr-x
