Xiaoyu Yao created HADOOP-17079: ----------------------------------- Summary: Optimize UGI#getGroups by adding UGI#getGroupsSet Key: HADOOP-17079 URL: https://issues.apache.org/jira/browse/HADOOP-17079 Project: Hadoop Common Issue Type: Improvement Reporter: Xiaoyu Yao Assignee: Xiaoyu Yao
UGI#getGroups has been optimized with HADOOP-13442 by avoiding the List->Set->List conversion. However the returned list is not optimized to contains lookup. This ticket is opened to add a UGI#getGroupsSet and use Set#contains() instead of List#contains() to speed up large group look up. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
