-----------------------------------

             Summary: Document types of permission checks performed for HDFS 
operations.
                 Key: HDFS-9552
                 URL: https://issues.apache.org/jira/browse/HDFS-9552
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: documentation
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


The HDFS permissions guide discusses our use of a POSIX-like model with read, 
write and execute permissions associated with users, groups and the catch-all 
other class.  However, there is no documentation that describes exactly what 
permission checks are performed by user-facing HDFS operations.  This is a 
frequent source of questions, so it would be good to document this.
