apahce solr for Ranger is must?

apahce solr for Ranger is must?

Master Collaborator

I am using HDP2.5.0

two questions :

1- do I have to install apache Solr for Ranger ?

2- If its mandatory then does the Ranger installation from Ambari takes care of it or do I have to install it manually on command line?

Re: apahce solr for Ranger is must?

1] For Ranger auditing, HDP 2.5 supports only Solr and HDFS. To view audits in Ranger UI, Solr is required.

2] Ambari Infra Solr is one option. The other option is to manage Solr outside of Ambari.

will Ranger installation also install Solr when I add the Ranger service in Ambari?

@Sami Ahmad , no, Ranger does not install Solr for you. What @vperiasamy was referring to, is service "Ambari Infra". This service runs a SolrCloud under the hood, and if you configure Ranger to store audits in SolrCloud it will by default pick up this SolrCloud instance.

To put it in a nutshell: you need service "Ambari Infra" if you do not want to setup/maintain a dedicated, additional SolrCloud environemnt.
