HDP services run under the ownership of a Windows user account. The HDP installer
establishes a hadoop user as follows:
If the
hadoopuser account does not exist, HDP installer automatically creates a local user with random password.If the
hadoopuser account already exists, HDP installer changes the current password to a new random password.
The random password is passed on the command line throughout the install process, and then discarded. The administrator can change the password later, but it must be changed both in the user configuration and in the service objects installed on each machine via Service Manager.
