3.4. (Optional) Create Hadoop user

HDP services run under the ownership of a Windows user account. The HDP installer establishes a hadoop user as follows:

  • If the hadoop user account does not exist, HDP installer automatically creates a local user.

  • If the hadoop user account already exists, HDP installer uses the current password.

You can specify the Hadoop user password in the MSI command line. 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.
