Weiwei Yang commented on HADOOP-7064: ------------------------------------- I have uploaded a patch in HDFS-8312 to demonstrate this issue, appreciate if someone can take a look and let me know if my thought looks good. Many thanks. > FsShell does not properly check permissions of files in a directory when > doing rmr > ---------------------------------------------------------------------------------- > > Key: HADOOP-7064 > URL: https://issues.apache.org/jira/browse/HADOOP-7064 > Project: Hadoop Common > Issue Type: Bug > Components: fs > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
