#CLOUDERA APACHE LUCENE UPGRADE#
Starting in Cloudera Enterprise 6, Cloudera provides a Solr configuration migration script to simplify the upgrade process by providing upgrade instructions tailored to yourĬonfiguration. Additionally, admins had to determine whether theyĬould upgrade existing indexes, or if they had to re-index the raw data. Review the Solr release notes and manually identify configuration changes needed to address incompatibilities or to take advantage of new features. It has long been a challenge to understand the implications of a Solr upgrade. Do not upgrade your production Cloudera Search environments to CDH 6 until you have tested the migrated configuration with CDH 6 on a testing or development cluster.ĭespite widespread enterprise adoption, Solr lacks automated upgrade tooling. Warning: Although the configuration migration script addresses known incompatibilities, there might be incompatible configurations that are notĭetected by the script. Solr Configuration Migration Script Overview You can continue indexing to existing collections (except Lily HBase indexing) until otherwise instructed.
Do not create, delete, or modify any collections for the duration of the migration and upgrade. For instructions, see Migrating HBase Indexer Sentry Policy Files to the Sentry Service. CDH versions lower than 5.14.0 do not support using the Sentry Service with the HBase If you are upgrading from CDH 5.14.0 or higher, migrate to the Sentry Service before upgrade. To do so, uncheck the box labeled Enable Sentry Authorization using Policy Files ( Key-Value Store Indexer service > Configuration > Category > Policy File Based Sentry). If you are upgrading from a CDH version lower than 5.14.0, disable Sentry for the Lily HBase Indexer service before upgrading. If you are using the Lily HBase Indexer service with Apache Sentry policy files:. If you are using the Lily HBase Indexer service, stop writing to any tables that are indexed into Solr, and stop the Lily HBase Indexer service ( Key-Value Store Indexer service > Actions > Stop). For instructions onĬreating a nf file, see Configuring a nf File. If you are using Kerberos, create a nf file for the Search service superuser ( solr by default). Plan for an outage for any applications or services that use your Search deployment until you have completed re-indexing after the upgrade. Includes adding or removing Solr Server hosts, moving Solr Server roles between hosts, changing hostnames, and so on. Make sure that no configuration changes are made to Cloudera Search for the duration of the migration and upgrade. Stop making changes to your Cloudera Search environment. If you are using Apache Sentry with policy files, complete the steps in Migrating from Sentry Policy Files to the. For instructions on upgrading to Cloudera Manager 6, see Upgrading Cloudera 
Make sure you are running Cloudera Manager 6.0 or higher. A Solr service without collections causes the upgrade process to If there are no collections added to Solr, you must remove it from the cluster before you start the upgrade process. Production Cloudera Search environments to CDH 6 until you have tested the migrated configuration with CDH 6 on a testing or development cluster. Plan downtime for any applications or services that use your SearchĪlthough the configuration migration script addresses known incompatibilities, there might be incompatible configurations that are not detected by the script. Make sure that the source data that was used to index your collections is still available before upgrading.

The following procedures update only your Solr configuration and metadata to be compatible with the new Solr version. Warning: Due to changes in the underlying Apache Lucene file format between the CDH 5 and CDH 6 versions of Solr, it is not possible to directly
