----------------------------------------
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.
