@Muthukumar S I am sure if it was a BUG then, hortonworks would have notified its customers having said that, it might sound trivial but try to go over your code, personally I don't see the issue with HDP 2.4 but if I may ask why haven't you upgraded? [root@nakuru ~]# su - usera
[usera@nakuru ~]$ id
uid=1024(usera) gid=1024(usera) groups=1024(usera),507(data_team)
[usera@nakuru ~]$ hadoop fs -ls /abc/month=12
Found 2 items
-rw-r--r--+ 3 abiuser dfsusers 151 2018-01-11 13:00 /abc/month=12/acltest2.txt
-rw-r--r-- 3 abiuser dfsusers 249 2018-01-11 12:38 /abc/month=12/file1.txt
[usera@nakuru ~]$ hdfs dfs -getfacl -R /abc/month=12/
# file: /abc/month=12
# owner: abiuser
# group: dfsusers
user::rwx
group::r-x

[usera@nakuru ~]$ Since I reproduced your use case and provided the solution, I think its better you accept and close the thread. The hortonworks demo HDFS ACLS: fine-grained permissions for hdfs files in hadoop was delivered using HDP 2.4 , so at times when I get in such a situation I ask a friend to crosscheck my code you might have forgotten something. Cheers !
