[jira] [Created] (HDFS-9552) Document types of permission checks performed for HDFS operations.

Chris Nauroth created HDFS-9552:
-----------------------------------

             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.
