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https://cwiki.apache.org/confluence/display/Hive/HiveClient#HiveClient-Python appears to be outdated.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

None of the answers demonstrate how to fetch and print the table headers. Modified the standard example from PyHive which is widely used and actively maintained.

from pyhive import hive
cursor = hive.connect(host="localhost", 
                      port=10000, 
                      username="shadan", 
                      auth="KERBEROS", 
                      kerberos_service_name="hive"
                      ).cursor()
cursor.execute("SELECT * FROM my_dummy_table LIMIT 10")
columnList = [desc[0] for desc in cursor.description]
headerStr = ",".join(columnList)
headerTuple = tuple(headerStr.split (",")
print(headerTuple)
print(cursor.fetchone())
print(cursor.fetchall())
