Follow the steps below to enable impersonation in your MapR installation.
- Open the
core-site.xmlfile in a text editor.
Add the these hadoop.proxyuser properties:
*) allows the mapr superuser to impersonate any user in any group.
*) allows the mapr superuser to connect from any host to impersonate a user.
Do not use anything other than a single asterisk here. Other parts of MapR ignore the values here and treat them as if each is set to a single asterisk.
- Close the file, saving changes.
