> HiveStrictManagedMigration utility should update DB/Table location as last

>          Issue Type: Sub-task
>            Reporter: Jason Dere

>
> 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
