Default password for 'spark' user?

[#1]

I tried running 'start-slaves.sh' as 'spark' user but while connecting to slave machine, it's asking for password. I do have the privilege to change the password for 'spark' user but doing so might stop some processes. Could you please suggest something to tackle this issue?

Then as root do switch command

# su - spark

Run your job

Unfortunately, i don't have access to root. I am in sudoers list btw.

"spark" user is a service user, hence it has no password. you should switch user either from root or sudo user.
