Key: HDFS-9511 URL: https://issues.apache.org/jira/browse/HDFS-9511 Project: Hadoop HDFS Issue Type: Bug Components: security Affects Versions: 2.7.1 Reporter: KWON BYUNGCHANG Priority: Minor
My environment does not allow add user/group. I can't rely os user/group mechanism. and I don’t want to show below log. {code} 2015-11-26 13:21:48,486 WARN security.UserGroupInformation (UserGroupInformation.java:getGroupNames(1521)) - No groups available for user hello {code} I append {{org.apache.hadoop.security.SimpleUserGroupsMapping}}. It is very simple. group of some user is user. user and group are same. if some users should be another group that is different with user name, use {{hadoop.user.group.static.mapping.overrides=user1=group;user2=group}} problem is when {{hdfs dfsadmin -refreshUserToGroupsMappings}} , {{yarn rmadmin -refreshUserToGroupsMappings}}, it does not reload that config. Thank you. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
