How to Update/Drop a Hive Partition?

Question

After adding a partition to an external table in Hive, how can I update/drop it?

Answer 1

You may also need to make database containing table active

use [dbname]

otherwise you may get error (even if you specify database i.e. dbname.table )

FAILED Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Unable to alter partition. Unable to alter partitions because table or database does not exist.
