Delete Hive Partition Data: Step-by-Step Guide

To delete Hive partition data, you can follow these steps:

Open the Hive terminal or connect to the Hive database using a Hive management tool like Hue.

Use the following command to view the current partition data:

SHOW PARTITIONS table_name;

Locate the partition that needs to be deleted, and then use the following command to delete the data in that partition:

ALTER TABLE table_name DROP IF EXISTS PARTITION (partition_column=value);

Among them, table_name represents the table name, partition_column represents the partition column name, and value represents the partition value to be deleted.

After confirming the deletion operation, use the following command to clean up invalid partition data:

MSCK REPAIR TABLE table_name;

This will allow you to delete specific partition data from a Hive table. Please make sure to backup important data before executing the deletion operation to prevent any data loss.
