my SOLR server is up and running but when ranger tries to connect to it I get error :

iam not sure if the ranger audit url I am using is correct since its unreachable "http://hadoop1:8983/solr/ranger_audits" ?

if I try to go to this url I get the error

HTTP ERROR 404
Problem accessing /solr/ranger_audits. Reason:
    Not Found

@Sami Ahmad - You've got a couple of things going on. It looks like you are not using the Ambari Infra Solr installation. To use an external Solr, follow these instructions. You'll be using scripts rather than the UI to create the collection.

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.3/bk_security/content/solr_ranger_configure_s...

The version of Solr you as using may not work with Ambari. You should use 5.2.1 or 5.5.2 to be consistent with what's released with HDP. If you go to 6.x, being a major release, you may encounter significatn issues. Also note that $SOLR/server/lib is not the directory where your config files wold belong with Solr anyway. Normally you'll put them into a "config" directory somewhere. They cannot be in a directory with binary files or you will definitely encounter issues when it tries to load the directory into Zookeeper and then you have a bigger mess to clean up.

@Sami Ahmad Which version of Ambari are you on? Ambari Infra is only in Ambari 2.4.0 and later.

aliyesami · ‎12-05-2016

I just checked and Ambari Infra is already installed in my HDP2.5 cluster .

james_jones · ‎12-06-2016

Are you also using Ambari 2.4.x? I believe Ambari Infra is shipped wit Ambari 2.4.x, not HDP 2.5. It's sort of like Ambari Metrics is part of Ambari but not directly part of HDP, even though it works with HDP. Assuming you have Ambari 2.4.x, do you don't see "Ambari Infra" when you select Add Service (it does not have the name Solr in it in Ambari)?

Glad you have it worked out. Somehow I missed your last post stating that it is already installed, so my previous comment is OBE.
