We have a Old Cluster with HDP 2.0.6 (Hive 0.12.0).. New Cluster with HDP 2.3.2 (Hive 1.2.1). We need to hive query the same tables in new environment and old environment after data forklift in same manner (implying database names, partitioning, etc. work). We migrated all the hdfs data over using distcp.

If its just a migration, you can make a copy of your old database and then point the HDP 2.3.2 cluster to the copy of your old database. Before starting the Hive services upgrade the hive database by using schemaTool. You can use metatool to update the HDFS locations to the new cluster. Start the hive services.

Do we have a way to generate the DDLs for hive databases ?
