Can somebody update on this, I was installing HAWQ in HDP sandbox in the standalone machine, but after completing half of that I stuck to the below step.
Trying to add the HDB repository to the Ambari server and had the issue with user name and password used.
I was using the same username and password that sandbox provides.
reference link for installation instruction article [failing point at 5] - http://hdb.docs.pivotal.io/201/hdb/install/install-ambari.html
Any suggestion is highly appreciated.


Make sure you are giving ambari admin username and password .Default is user "admin" and password is "admin"
