Configuring Apache Solr in Apache Ambari

Apache Ranger uses Apache Solr for audit log aggregation and integration. Apache Solr is a search engine and uses resources heavily, such as CPU and memory (at least 32 GB), and about 1 TB for storing index data. Apache Solr should be assigned to one of the less loaded nodes in your cluster, such as un1 with storage of at least 1 TB.
