Validating Atlas
On Atlas Metadata Server host, run the following command to start ATLAS server:
/usr/hdp/<hdp-version>/atlas/bin/atlas_start.py –port 21000
Open the Atlas Dashboard by visiting the following url:
http://<ATLAS_Metadata_Server_FQDN>:21000/
To validate Atlas is running properly in an unsecure configuration, access the Atlas REST API by invoking the following command:
curl -sL -w "%{http_code} %{url_effective}\\n" "http://<ATLAS-HOST>:21000" -o /dev/null
where ATLAS-HOST is the FQDN of the host where Atlas has been installed. The expected response should return a 200 response along with the URL that was accessed; similar to:
200 http://localhost:21000/
