Bootstrap Solr collections after upgrading the cluster

As a part of the upgrade process, you must perform bootstrapping of Solr collections using Cloudera Manager to recreate the empty collections.

As of Cloudera Runtime 7.1.4, the Solr upgrade script provided by Cloudera does not perform bootstrapping of Solr collections as part of the upgrade process. You need to perform this step using Cloudera Manager to recreate the empty collections.
In Cloudera Manager > Clusters, select the Solr service. Click Actions and click Botostrap Solr Collections.


After the bootstrap porcess completes, you find the recreated empty collections in Solr.
