Description

Owner & group attributes are missing when you list oss objects via hadoop command:

Found 6 items
drwxrwxrwx - 0 2018-08-01 21:37 /1024
drwxrwxrwx - 0 2018-10-30 11:07 /50
-rw-rw-rw- 1 94070 2018-11-08 21:48 /a
-rw-rw-rw- 1 2441079322 2018-10-31 10:14 /lineitem.csv
drwxrwxrwx - 0 1970-01-01 08:00 /tmp
drwxrwxrwx - 0 1970-01-01 08:00 /user

 

The result should like below(hadoop fs -ls hdfs://master:8020/):

Found 5 items
drwxr-xr-x - hbase hbase 0 2018-11-18 17:31 hdfs://master:8020/hbase
drwxrwxrwt - hdfs supergroup 0 2018-10-30 11:07 hdfs://master:8020/tmp
drwxr-xr-x - hdfs supergroup 0 2018-10-30 10:39 hdfs://master:8020/user

However, oss objects do not have owner & group attributes like hadoop files,  so we assume both owner & group are the current user at the time the FS was instantiated.
