> URL: https://issues.apache.org/jira/browse/HDFS-4679
> Project: Hadoop HDFS
> Issue Type: Improvement

>
> 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
