Hi @Satish Sarapuri

this link provide details on how to reset password for other users, not for root user. I want to reset password for "root" user.

Login to the docker instance as root with default password as "hadoop"

ssh root@ -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.

At the Docker Level:

Did you try the following:

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:
