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https://cwiki.apache.org/confluence/display/Hive/HiveClient#HiveClient-Python appears to be outdated.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

It is a common practice to prohibit for a user to download and install packages and libraries on cluster nodes. In this case solutions of @python-starter and @goks are working perfect, if hive run on the same node. Otherwise, one can use a beeline instead of hive command line tool. See details

#python 2
import commands

cmd = 'beeline -u "jdbc:hive2://node07.foo.bar:10000/..." -e "SELECT * FROM db_name.table_name LIMIT 1;"'

status, output = commands.getstatusoutput(cmd)

if status == 0:
   print output
else:
   print "error"

.

#python 3
import subprocess

cmd = 'beeline -u "jdbc:hive2://node07.foo.bar:10000/..." -e "SELECT * FROM db_name.table_name LIMIT 1;"'

status, output = subprocess.getstatusoutput(cmd)

if status == 0:
   print(output)
else:
   print("error")
