Summary: ShellBasedUnixGroupMapping should support group names with space Key: HADOOP-12505 URL: https://issues.apache.org/jira/browse/HADOOP-12505 Project: Hadoop Common Issue Type: Bug Reporter: Wei-Chiu Chuang Assignee: Wei-Chiu Chuang In a typical configuration, group name is obtained from AD through SSSD/LDAP. AD permits group names with space (e.g. "Domain Users"). Unfortunately, the present implementation of ShellBasedUnixGroupMapping parses the output of shell command "id -Gn", and assumes group names are separated by space. This could be achieved by using a combination of shell scripts, for example, bash -c 'id -G weichiu | tr " " "\n" | xargs -I % getent group "%" | cut -d":" -f1' But I am still looking for a more compact form, and potentially more efficient one. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
