Hi, Sahara doesn't have user's username and password, only user's token, that could expire in some time. The simplest installation requires you to specify credentials explicitly, but you could configure Sahara to access Swift using proxy user and trusts, more info in docs - http://docs.openstack.org/developer/sahara/userdoc/advanced.configuration.guide.html#object-storage-access-using-proxy-users
In this case, you don't need to specify credentials at all, Sahara will create a trust for you and will use it to grant needed permissions to automatically created user, that will be passed to Hadoop cluster to be used to access data in Swift. Thanks.
