Transitioning Cloudera Search configuration before upgrading to Cloudera Runtime
If your CDH cluster includes Cloudera Search, there are steps you need to take before transitioning your cluster to CDP Private Cloud Base. Read these instructions even if the Cloudera Search instance installed in your cluster is not in use to avoid compromising your entire upgrade procedure.
As Cloudera Search is included in Cloudera Runtime 7.1.1 or higher, upgrading from CDH 5 to Cloudera Runtime 7.1.1 or higher upgrades Cloudera Search as well. If you are upgrading to Cloudera Runtime 7.1.1 or higher from CDH 5, and you are using Cloudera Search, you must complete certain preparatory tasks.
Cloudera Search that is shipped with Cloudera Runtime 7.1.1
or higher uses Apache
Solr 8, which has certain incompatibilities with previous Solr versions. To facilitate the
upgrade, Cloudera provides a Solr configuration transition script,
solr-upgrade.sh. This script is included with Cloudera Manager. You must
upgrade to Cloudera Manager 7.1 or higher before you can start the Cloudera Search
Use the following procedures to migrate your Cloudera Search configuration before upgrading a cluster to Cloudera Runtime 7.1.1 or higher. The migration script cannot upgrade the Lucene index files. After upgrading, you must reindex your collections. For more information, see Reindexing in Solr in the Apache Solr wiki.
