--------------------------------------
Summary: Optimize Ranger code for authorization of HDFS commands
getContentSummary and delete
Key: RANGER-1695
URL: https://issues.apache.org/jira/browse/RANGER-1695
Project: Ranger
Issue Type: Bug
Components: Ranger
Affects Versions: 0.7.1
Reporter: Abhay Kulkarni
Assignee: Abhay Kulkarni
Fix For: master
HDFS commands such as getContentSummary and delete require Ranger to authorize
access to entire directory hierarchy rooted at the directory passed in as
argument. Ranger could optimize this code by pruning the directory tree
whenever a sub-directory, and directory hierarchy rooted in it, is authorized
for requested access. This could potentially save many spurious authorization
API calls with Ranger policy engine.
Also, it will be useful to gather and log performance metrics for the Ranger
authorization API call for every Ranger plugin.
