Python interface to Hive

Project description

Project is currently unsupported


PyHive is a collection of Python DB-API and SQLAlchemy interfaces for Presto , Hive and Trino.



from pyhive import presto  # or import hive or import trino
cursor = presto.connect('localhost').cursor()  # or use hive.connect or use trino.connect
cursor.execute('SELECT * FROM my_awesome_data LIMIT 10')
print cursor.fetchone()
print cursor.fetchall()

DB-API (asynchronous)

from pyhive import hive
from TCLIService.ttypes import TOperationState
cursor = hive.connect('localhost').cursor()
cursor.execute('SELECT * FROM my_awesome_data LIMIT 10', async=True)

status = cursor.poll().operationState
while status in (TOperationState.INITIALIZED_STATE, TOperationState.RUNNING_STATE):
    logs = cursor.fetch_logs()
    for message in logs:
        print message

    # If needed, an asynchronous query can be cancelled at any time with:
    # cursor.cancel()

    status = cursor.poll().operationState

print cursor.fetchall()

In Python 3.7 async became a keyword; you can use async_ instead:

cursor.execute('SELECT * FROM my_awesome_data LIMIT 10', async_=True)


First install this package to register it with SQLAlchemy, see entry_points in

from sqlalchemy import *
from sqlalchemy.engine import create_engine
from sqlalchemy.schema import *
# Presto
engine = create_engine('presto://localhost:8080/hive/default')
# Trino
engine = create_engine('trino+pyhive://localhost:8080/hive/default')
# Hive
engine = create_engine('hive://localhost:10000/default')

# SQLAlchemy < 2.0
logs = Table('my_awesome_data', MetaData(bind=engine), autoload=True)
print select([func.count('*')], from_obj=logs).scalar()

# Hive + HTTPS + LDAP or basic Auth
engine = create_engine('hive+https://username:password@localhost:10000/')
logs = Table('my_awesome_data', MetaData(bind=engine), autoload=True)
print select([func.count('*')], from_obj=logs).scalar()

# SQLAlchemy >= 2.0
metadata_obj = MetaData()
books = Table("books", metadata_obj, Column("id", Integer), Column("title", String), Column("primary_author", String))
inspector = inspect(engine)

with engine.connect() as con:
    data = [{ "id": 1, "title": "The Hobbit", "primary_author": "Tolkien" },
            { "id": 2, "title": "The Silmarillion", "primary_author": "Tolkien" }]
    con.execute(books.insert(), data[0])
    result = con.execute(text("select * from books"))

Note: query generation functionality is not exhaustive or fully tested, but there should be no problem with raw SQL.

Passing session configuration

hive.connect('localhost', configuration={'hive.exec.reducers.max': '123'})
presto.connect('localhost', session_props={'query_max_run_time': '1234m'})
trino.connect('localhost',  session_props={'query_max_run_time': '1234m'})
# SQLAlchemy
    connect_args={'protocol': 'https',
                  'session_props': {'query_max_run_time': '1234m'}}
    connect_args={'protocol': 'https',
                  'session_props': {'query_max_run_time': '1234m'}}
    connect_args={'configuration': {'hive.exec.reducers.max': '123'}},
# SQLAlchemy with LDAP
    connect_args={'auth': 'LDAP'},


Install using

  • pip install 'pyhive[hive]' or pip install 'pyhive[hive_pure_sasl]' for the Hive interface

  • pip install 'pyhive[presto]' for the Presto interface

  • pip install 'pyhive[trino]' for the Trino interface

Note: 'pyhive[hive]' extras uses sasl that doesn’t support Python 3.11, See github issue. Hence PyHive also supports pure-sasl via additional extras 'pyhive[hive_pure_sasl]' which support Python 3.11.

PyHive works with




  • Please fill out the Dropbox Contributor License Agreement at and note this in your pull request.

  • Changes must come with tests, with the exception of trivial things like fixing comments. See .travis.yml for the test environment setup.

  • Notes on project scope:

    • This project is intended to be a minimal Hive/Presto client that does that one thing and nothing else. Features that can be implemented on top of PyHive, such integration with your favorite data analysis library, are likely out of scope.

    • We prefer having a small number of generic features over a large number of specialized, inflexible features. For example, the Presto code takes an arbitrary requests_session argument for customizing HTTP calls, as opposed to having a separate parameter/branch for each requests option.

Tips for test environment setup

You can setup test environment by following .travis.yaml in this repository. It uses Cloudera’s CDH 5 which requires username and password for download. It may not be feasible for everyone to get those credentials. Hence below are alternative instructions to setup test environment.

You can clone this repository which has Docker Compose setup for Presto and Hive. You can add below lines to its docker-compose.yaml to start Trino in same environment:

    image: trinodb/trino:351
        - "18080:18080"
        - ./trino:/etc/trino

Note: ./trino for docker volume defined above is trino config from PyHive repository

Then run::

docker-compose up -d


Run the following in an environment with Hive/Presto:

virtualenv --no-site-packages env
source env/bin/activate
pip install -e .
pip install -r dev_requirements.txt

WARNING: This drops/creates tables named one_row, one_row_complex, and many_rows, plus a database called pyhive_test_database.

Updating TCLIService

The TCLIService module is autogenerated using a TCLIService.thrift file. To update it, the file can be used: python <TCLIServiceURL>. When left blank, the version for Hive 2.3 will be downloaded.
