user group mapping dose not work as I expected

New Contributor

I use kerberized cluster backed by openldap using sssd on centos7

and I configured user as following.

 

[root@localhost sssd]# hdfs groups zako
zako : datalaker


[root@localhost sssd]# hadoop org.apache.hadoop.security.UserGroupInformation
Getting UGI for current user
User: zako/localhost.localadmin@YUKI.COM
Group Ids: 
Groups: datalaker 
UGI: zako/localhost.localadmin@YUKI.COM (auth:KERBEROS)
Auth method KERBEROS
Keytab false
============================================================

[root@localhost sssd]# id -gn zako
datalaker


[root@localhost sssd]# id -Gn zako
datalaker

 

I expected zako:datalaker as user:group by executing hadoop mkdir command.

however , I got an following result.

[root@localhost sssd]# hadoop fs -mkdir /tmp/hoge && hadoop fs -ls /tmp && hadoop fs -rmr -skipTrash /tmp/hoge
Found 4 items
d--------- - hdfs supergroup 0 2019-05-07 23:57 /tmp/.cloudera_health_monitoring_canary_files
drwx-wx-wx - hive supergroup 0 2019-05-05 13:51 /tmp/hive
drwxr-xr-x - zako supergroup 0 2019-05-22 10:43 /tmp/hoge  <- zako:datalaker is that I excpect..
drwxrwxrwt - mapred hadoop 0 2019-05-05 13:39 /tmp/logs
rmr: DEPRECATED: Please use '-rm -r' instead.
Deleted /tmp/hoge

How can I rectify the problem.

 

Thanks,Yuki
