Hi @steven-matison The issue got fixed after making below 2 changes in /etc/krb5.conf file 1. Issue was a include line in my /etc/krb5.conf file which was not valid. Removed below from /etc/krb5.conf "includedir /etc/krb5.conf.d/" 2. On macOS the default client does not fall back to TCP. In krb5.conf prefix kdc value with tcp/ to force the client to use TCP if your corporate network blocks UDP. kdc = tcp/kdc.example.com:88 Regards, Banshi.

Hi @steven-matison You are right. I have replaced actual REALM with EXAMPLE.COM while posting. I have checked connectivity using "nc -zv" and "ping" command. Connectivity is fine. ==== nc -zv <kdc_server_VIP> <KDC_Port> Connection to xxxxxxxx port xxxxxx [tcp/sqlexec] succeeded! ==== --- <kdc_server_VIP> ping statistics --- 13 packets transmitted, 12 packets received, 7.7% packet loss ==== "kinit: krb5_get_init_creds: unable to reach any KDC in realm EXAMPLE.COM, tried 0 KDCs" By seeing the above error, I feel it's not able to locate the krb5.conf file. When we run kinit command, is it referring to /etc directory for krb5.conf file or some other location in Mac machine? Regards, Banshi.

Hi Team, Thank you very much for promptly responding and providing useful solution/direction. While testing, app team reported that child dir/files are having r-x (for dir) and r--(files) for Others. Looks like ACL are not getting inherited to child dir and files. Can you confirm if ACL should inherit to child dir and files or not? Is there any other configuration that I need to check and modify? Regards, Banshi.

Hi @Shelton, Thank you very much for sharing the exact commands. Only thing that needs to change in the shared commands is - others should be other Here is the command that worked for me. $ hdfs dfs -setfacl -m other::--- /path/to/dir Regards, Banshi.

Hi @tusharkathpal , Thank you very much. I tested it. It worked for ownership. I want 750 permission on the directory recursively. However it's not reflecting in case of new file. Is there a way to do that? Idea is to restrict 'others' from accessing the file/dir. Regards, Banshi.

Hi All, In our CDP 7.1.2 cluster, default ownership of any file or directory is <user>and supergroup. One application team wants their data owner group to be their own group in stead of supergroup. for example: Let the app team user is 'abc' and group is 'abc'. Currently owner and group for any file/dir in HDFS is abc:supergroup. They want it to be abc:abc. Please suggest how to achieve this so that any new file created by abc user will have ownership as abc:abc. Regards, Banshi.

Regards, Banshi.

Hi All, Good Afternoon. We have CDH 5.14 and Impala 2.11 in one of our Cloudera cluster. We have a requirement to upgrade Impala to 3.2 in the same cluster. Please suggest us the best way to achieve this. Can we just upgrade Impala without upgrading CDH. Regards, Banshi.
