    Description

      Different operations performs checks in different order. I propose consistently checking the following in namenode operations:

      1. Print debug log related to the operation
      2. validate the input parameters, file names
      3. Grab read or write lock
        • check if system is ready for read or write operation
        • check if system is in safemode (for write operations)
        • check permissions to see if the user is owner, has access or is super user privileges
      4. Release the lock
