'hdfs://ns1/apps/hive/warehouse/tpcds_bin_partitioned_orc_10.db';
hive> ALTER TABLE tpcds_bin_partitioned_orc_10.store_sales SET LOCATION
'hdfs://ns1/apps/hive/warehouse/tpcds_bin_partitioned_orc_10.db/store_sales';
-
On the Hive Metastore node, log in as the HDFS superuser.

Set STACK_VERSION to the HDP version you are running.
