No default admin / user after installation - can't login or register?

Usually after initial install of arcadia, a default admin account is created on the system to allow registration and initial login & setup through the Arcadia UI console / browser.

In case that doesn’t happen, here are a few things you can try:

  1. If using CDH parcel installation through Cloudera Manager you can try re-initializing: as shown here:

  2. Alternatively, you can use command line utility. Make sure the visualization server has been started. Then SSH to the host running the visualization server and run the below commands:

    > sudo su arcadia
    > /opt/cloudera/parcels/ARCADIAENTERPRISE/lib/arcviz/arcviz createsuperuser

For Hortonworks installs you can use these commands:

su arcadia
cd /opt/arcadia/lib/arcviz 
./arcviz createsuperuser
