5.3. Optional - Create Hadoop user

HDP installer takes the following actions to create hadoop user for your environment:

  • If user hadoop does not exist, HDP installer automatically creates a local user with random password.

  • If the user hadoop already exists, HDP installer will change the current password to a new random password. The random password is passed on the command line throughout the install process, then discarded. Administrator can change the password later, but it must be done both in the user configuration and in the service objects installed on each machine via Service Manager.
