Enabling Impersonation for the HPE Ezmeral Data Fabric Superuser

Provides a procedure necessary to implement superuser impersonation.

To enable impersonation in your HPE Ezmeral Data Fabric installation:

  1. Open the following file in a text editor:
  2. Add the following hadoop.proxyuser properties:

    The hosts setting (*) allows the mapr superuser to connect from any host to impersonate a user.

    The groups setting (*) allows the mapr superuser to impersonate any user in any group.

    Note: Do not use anything other than a single asterisk here. Other parts of HPE Ezmeral Data Fabric ignore the values here and treat them as if each is set to a single asterisk.
  3. Close the file, saving any changes that you made.
