Xiaoyu Yao updated HADOOP-17079: -------------------------------- Status: Patch Available (was: Open) > 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 > Priority: Major > > 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 > while minimize List->Set conversions in Groups#getGroups() call. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
