The SYNC command can be used to migrate legacy external Apache Hive tables to Unity Catalog.

When you run SYNC in a Databricks notebook, it fails with a mismatched input 'schema' expecting 'MATERIALIZED' error.

SYNC schema <target UC catalog>.<target UC schema> from hive_metastore.<hive schema> DRY RUN

com.databricks.backend.common.rpc.DatabricksExceptions$SQLExecutionException: org.apache.spark.sql.catalyst.parser.ParseException: mismatched input 'schema' expecting 'MATERIALIZED'(line 1, pos 5)


This error occurs if Unity Catalog is not enabled on your cluster.


Verify that Unity Catalog is enabled in your workspace and on your clusters.

Unity Catalog is supported with Single user and Shared access mode on clusters running Databricks Runtime 11.3 LTS and above. Unity Catalog is not supported on No isolation shared clusters.
