I have configured Ranger with Ranger-admin and Hadoop , HDFS  plugins. 

 

I can access the basic url,
curl -u rangeradmin:rangeradmin -i -X GET http://127.0.0.1:6080
HTTP/1.1 302 Found
Set-Cookie: RANGERADMINSESSIONID=6A1E7311C911AE876D02359679222E24; Path=/; HttpOnly

but on accessing other urls it fails:

 

 

curl -u rangeradmin:rangeradmin -i -X GET http://127.0.0.1:6080/service/plugins/policies/service/1

I have not used Ambari  UI, instead built ranger from sources and installed the hadoop , ranger-admin and HDFS plugins , Is there any way to check Ranger's REST apis with Ambari

 

This is my configuration inside install.properties of ranger-2.1.0-SNAPSHOT-admin , after which I installed ranger-admin plugin

 

policymgr_external_url=http://localhost:6080
policymgr_http_enabled=true
policymgr_https_keystore_file=
policymgr_https_keystore_keyalias=rangeradmin
policymgr_https_keystore_password=rangeradmin

 

With this user name and password, I get the following response:

 

curl -u rangeradmin:rangeradmin -i -X GET http://127.0.0.1:6080/login.jsp
HTTP/1.1 200 OK

@ranger 

Even if you have build ranger from source... before making the API call you should validate the following:

 

Are you really sure that the credentials that you are entering is correct?

 

1. Are you able to login to Ranger UI with that credential?  (this is the verify if your credentials are correct or not) ?    

 

2. Do you see "Bad Credentials" message inside the "xa_portal.log" ?  Can you share the log?

Thanks for your guidance, Now when I try to login with rangeradmin:rangeradmin credentials ,

 

The username or password you entered is incorrect.

Though I have put rangeradmin as username and password inside ranger-admin/install,properties, it is not taking that,, Instead its taking admin:admin as credentials what I have setuo in Ambari server..

 

This I dont understand because ambari server I installed separately and never used Ambari to install Ranger, instead compiled Ranger from scratch.
