How to Access Hive via Python?

Question

https://cwiki.apache.org/confluence/display/Hive/HiveClient#HiveClient-Python appears to be outdated.

When I add this to /etc/profile:

export PYTHONP         


        

Answer 1

here's a generic approach which makes it easy for me because I keep connecting to several servers (SQL, Teradata, Hive etc.) from python. Hence, I use the pyodbc connector. Here's some basic steps to get going with pyodbc (in case you have never used it):

• Pre-requisite: You should have the relevant ODBC connection in your windows setup before you follow the below steps. In case you don't have it, find the same here

Once complete: STEP 1. pip install: pip install pyodbc (here's the link to download the relevant driver from Microsoft's website)

STEP 2. now, import the same in your python script:

import pyodbc

STEP 3. Finally, go ahead and give the connection details as follows:

conn_hive = pyodbc.connect('DSN = YOUR_DSN_NAME , SERVER = YOUR_SERVER_NAME, UID = USER_ID, PWD = PSWD' )

The best part of using pyodbc is that I have to import just one package to connect to almost any data source.
