Adding to the response. Take a look at the step-by-step instructions by @S Mahapatra in the link that Sonu provided.

@Satish Sarapuri

ssh root@127.0.0.1 -p 2222

The you can use "passwd" command to reset the password.

# passwd

Earlier, I have changed the default password "hadoop" to other password and forgot the changed one. Now,I want to reset the new password.

I tired with this default password "hadoop", but no luck.

@Satish Sarapuri

At the Docker Level:

Did you try the following:

$PASS='YOUR_NEW_PASSSWORD'
echo -e "$PASS\n$PASS" | sudo docker exec -i <container-id-or-name> passwd

Or may be docker command option "RUN echo newtestpassword | passwd root" in a Dockerfile

At the OS level:

In single user mode you should be able to do so. Can you please try this: https://www.liberiangeek.net/2014/09/reset-forgotten-root-password-centos-7-servers/

Please let me know if I am missing anything here or is there any other way to acheive the same.
