It depends how you created the user and his home directory? Using some API calls (like webhdfs) or some other tool?

While creating the Home directory Or the username if you will use \"hdpuser1\" then only you will see that kind of directory.

Example: (Correct Way)

[hdfs@sandbox ~]$ hdfs dfs -ls /user
Found 11 items
drwxr-xr-x   - admin     hadoop          0 2017-10-18 12:01 /user/admin
drwxrwx---   - ambari-qa hdfs            0 2017-06-25 10:43 /user/ambari-qa
drwxr-xr-x   - hbase     hdfs            0 2017-07-03 19:08 /user/hbase
drwxr-xr-x   - hcat      hdfs            0 2017-06-25 10:47 /user/hcat
drwxr-xr-x   - hdfs      hdfs            0 2017-10-25 07:27 /user/hdpuser1
drwxr-xr-x   - hive      hdfs            0 2017-10-24 06:40 /user/hive
drwxrwxr-x   - livy      hdfs            0 2017-08-14 17:46 /user/livy
drwxr-xr-x   - maria_dev hadoop          0 2017-10-21 11:01 /user/maria_dev
drwxrwxr-x   - oozie     hdfs            0 2017-08-05 14:40 /user/oozie
drwxr-xr-x   - root      hdfs            0 2017-10-21 13:41 /user/root
drwxrwxr-x   - spark     hdfs            0 2017-08-14 17:46 /user/spark

.

Incorrect Way:

[hdfs@sandbox ~]$ hdfs dfs -mkdir /user/\"hdpuser1\"
[hdfs@sandbox ~]$ hdfs dfs -ls /user
Found 12 items
drwxr-xr-x   - hdfs      hdfs            0 2017-10-25 07:28 /user/"hdpuser1"

Can you please let us know how you created that user & HDFS Directory (The exact command that you used)

Or you used some other tool / Java code to do that?

Or if you used any AD/LDAP to sync the users?

@ANSARI FAHEEM AHMED,

hdfs accepts directories with quotes. may be the directory was created using the below command

hdfs dfs -mkdir /user/\"hdpuser\"

Please check the screenshot.
