-----------------------------------
Summary: FsPermission symbolic parsing failed to detect invalid
argument
Key: HADOOP-14843
URL: https://issues.apache.org/jira/browse/HADOOP-14843
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.8.1, 2.7.4
Reporter: Jason Lowe
A user misunderstood the syntax format for the FsPermission symbolic
constructor and passed the argument "-rwr" instead of "u=rw,g=r". In 2.7 and
earlier this was silently misinterpreted as mode 0777 and in 2.8 it oddly
became mode 0000. In either case FsPermission should have flagged "-rwr" as an
invalid argument rather than silently misinterpreting it.
