[jira] [Created] (HADOOP-14843) FsPermission symbolic parsing failed to detect invalid argument

Jason Lowe created HADOOP-14843:
-----------------------------------

             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.
