             Summary: ALTER TABLE ... RENAME [OVERWRITE] [TO] to overwrite 
existing table
                 Key: HIVE-14795
             Project: Hive
          Issue Type: Improvement
          Components: Hive
    Affects Versions: 2.1.0, 2.0.0, 1.1.0, 1.2.0
            Reporter: Ruslan Dautkhanov

It would be great to Have in OVERWRITE option in Hive's rename command:

ALTER TABLE ... RENAME [OVERWRITE] [TO] to overwrite existing table, if it 

There are many commands like DROP TABLE IF EXISTS, LOAD DATA .. OVERWRITE that 
tell how to deal if table already exists.

We currently have to check in our ETL pipelines (outside of Hive) if table 
already exists and call different actions depending on that result.

It would simplify that logic quite a bit.

Closest in functionaility I found in MySQL:

This is not a compatibility breaking change.
