HDFS does not properly check permissions of files in a directory when doing rmr
-------------------------------------------------------------------------------
Key: HDFS-1495
URL: https://issues.apache.org/jira/browse/HDFS-1495
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: Alan Gates
In POSIX file semantics, the ability to remove an entry a file is determined by
whether the user has write permissions on the directory containing the file.
However, to delete recursively (rm -r) the user must have write permissions in
all directories being removed. Thus if you have a directory structure like
/a/b/c and a user has write permissions on a but not on b, then he is not
allowed to do 'rm -r b'. This is because he does not have permissions to
remove c, so the rm of b fails, even though he has permission to remove b.
However, 'hadoop fs -rmr b' removes both b and c in this case. It should
instead fail and return an error message saying the user does not have
permission to remove c. 'hadoop fs -rmr c' correctly fails.
