Configuring Sentry when connecting to Impala through Arcadia (Impala Delegation)

Configuration Steps:

  1. Go to the Impala service in Cloudera Manager, click “Configuration”
  2. Search for “proxy”
  3. Add the “arcadia” user to the Proxy User Configuration (see below)

In the example below, Impala was only setup to let Hue to delegate with it previously. We need to extend this option to also include the “arcadia” service user.

Before: hue=*

After: hue=*;arcadia=*

  1. Restart the Impala service.
