[#1]

using command
ALTER TABLE test table DROP PARTITION (START_DATE = DATE_ADD('2023-09-13', -13) )

Hive's ALTER TABLE DROP PARTITION statement doesn't directly accept DATE_ADD or similar functions inside the partition specification. Hive expects a static date value (e.g., 'YYYY-MM-DD') in the DROP PARTITION statement, not a function call.

As an alternative, You can create an HQL script and in that

• Calculate the Date Using DATE_ADD and Store it in a Variable:
• Use the Variable in the ALTER TABLE Statement:

As mentioned in the previous comment , it's advisable to use the static value. 

Example - 

CREATE TABLE test_table (
    id INT,
    name STRING
)
PARTITIONED BY (START_DATE STRING);

-- Add sample partitions for testing
ALTER TABLE test_table ADD PARTITION (START_DATE = '2023-09-01');
ALTER TABLE test_table ADD PARTITION (START_DATE = '2023-08-31'); -- This should be the target partition to drop
ALTER TABLE test_table ADD PARTITION (START_DATE = '2023-08-30');

compute the date in the shell and pass it to Hive.

# Set the base date and calculate the target date (13 days before the base date)
base_date="2023-09-13"
partition_date=$(date -d "$base_date - 13 days" +%Y-%m-%d)

# Log the computed date (optional)
echo "Dropping partition for date: $partition_date"

# Execute the Hive command to drop the partition
beeline -n hive -p hive -e "ALTER TABLE test_table DROP PARTITION (START_DATE = '$partition_date');show partitions test_table;"

Sample Run 

[root@ccycloud-2.blesc-15238.root.comops.site ~]# # Set the base date and calculate the target date (13 days before the base date)
[root@ccycloud-2.blesc-15238.root.comops.site ~]# base_date="2023-09-13"
[root@ccycloud-2.blesc-15238.root.comops.site ~]# partition_date=$(date -d "$base_date - 13 days" +%Y-%m-%d)
[root@ccycloud-2.blesc-15238.root.comops.site ~]#
[root@ccycloud-2.blesc-15238.root.comops.site ~]# # Log the computed date (optional)
[root@ccycloud-2.blesc-15238.root.comops.site ~]# echo "Dropping partition for date: $partition_date"
Dropping partition for date: 2023-08-31
[root@ccycloud-2.blesc-15238.root.comops.site ~]#
[root@ccycloud-2.blesc-15238.root.comops.site ~]# # Execute the Hive command to drop the partition
[root@ccycloud-2.blesc-15238.root.comops.site ~]# beeline -n hive -p hive -e "ALTER TABLE test_table DROP PARTITION (START_DATE = '$partition_date');show partitions test_table;"
