> When processing a database or table, the HiveStrictManagedMigration utility currently
changes the database/table locations as the first step in processing that database/table.
Unfortunately if an error occurs while processing this database or table, then there may still
be migration work that needs to continue for that db/table by running the migration again.
However the migration tool only processes dbs/tables that have the old warehouse location,
then the tool will skip over the db/table when the migration is run again.
>  One fix here is to set the new location as the last step after all of the migration
work is done:
>  - The new table location will not be set until all of its partitions have been successfully
migrated.
>  - The new database location will not be set until all of its tables have been successfully
migrated.
> For existing migrations that failed with an error, the following workaround can be done
so that the db/tables can be re-processed by the migration tool:
>  1) Use the migration tool logs to find which databases/tables failed during processing.
>  2) For each db/table, change location of of the database and table back to old location:
>  ALTER DATABASE tpcds_bin_partitioned_orc_10 SET LOCATION 'hdfs://ns1/apps/hive/warehouse/tpcds_bin_partitioned_orc_10.db';
>  ALTER TABLE tpcds_bin_partitioned_orc_10.store_sales SET LOCATION 'hdfs://ns1/apps/hive/warehouse/tpcds_bin_partitioned_orc_10.db/store_sales';
>  2) Rerun the migration tool
