Yiqun Lin updated HADOOP-13965:
-------------------------------
Description:
{code:title=Groups.java}
public Groups(Configuration conf, final Timer timer) {
impl =
ReflectionUtils.newInstance(
conf.getClass(CommonConfigurationKeys.HADOOP_SECURITY_GROUP_MAPPING,
ShellBasedUnixGroupsMapping.class,
GroupMappingServiceProvider.class),
conf);
...
}
{code}
The default value of setting {{hadoop.security.group.mapping}} is different in
code and config file. In file {{core-default.xml}}, it uses the class
{{JniBasedUnixGroupsMappingWithFallback}} and this should be the true value.
{code}
<property>
<name>hadoop.security.group.mapping</name>
<value>org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback</value>
<description>
Class for user to group mapping (get groups for a given user) for ACL.
The default implementation,
org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback,
will determine if the Java Native Interface (JNI) is available.....
