Hi @Sampath Kumar ,

From the output of chage -l hdfs i see your password of hdfs local user is expired. can you try to change

To resolve this issue, disable the expired password for the HDFS user, using the following command:

chage -m 0 -M 99999 -I -1 -E -1 hdfs

This command sets the following for the HDFS user:

Minimum Password Age to 0
Maximum Password Age to 99999
Password Inactive to -1
Account Expiration Date to -1

You can further explore the command chage in google and set the password policy accordingly.

and then try again with ambari.

Please see if this helps you. please accept answer if it did.
