Suresh Srinivas created HDFS-4679: ------------------------------------- Summary: Namenode operation checks should be done in a consistent manner Key: HDFS-4679 URL: https://issues.apache.org/jira/browse/HDFS-4679 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Reporter: Suresh Srinivas Assignee: Suresh Srinivas
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 -- This message is automatically generated by JIRA.
