Prerequisites
Before upgrading HDP Search, you should ensure that all indexing has stopped for Solr and all connectors, including Hadoop, Hive, and via Pig.
Stop Solr service.
Remove Solr service from Ambari.
Upgrade Ambari to 2.7.3 and HDP 3.1.4.0.
Verify that Ambari and HDP upgrade suceeded.
Upgrade Ambari Metrics, Smartsense, and Infra Solr.
Upgrade the Stack by removing the HDP Search 4.0.0 mpack and installing the Cloudera HDP Search 5.0.0 mpack.
Add the Solr service to your cluster, using the Ambari Web UI. Make sure that ZooKeeper, HDFS, Ranger and memory settings are consistent with the old installation.
