HDP Search 3.0 Known Issues
Please choose Map Reduce as the execution engine for Hive queries related to the Solr index. Tez will NOT work because Lucidwork's Hive SerDe does not yet support Hive 2 officially. It has been roadmapped for a future release. Currently, only Tez on Hive 1.x is supported.
Refer to the Ambari Troubleshooting Guide for additional information.
