Description
Different operations performs checks in different order. I propose consistently checking the following in namenode operations:
- Print debug log related to the operation
- validate the input parameters, file names
- 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
- Release the lock
