При подключении к Hive2 с использованием Python с кодом ниже:
import pyhs2
with pyhs2.connect(host='localhost',
port=10000,
authMechanism="PLAIN",
user='root',
password='test',
database='default') as conn:
with conn.cursor() as cur:
#Show databases
print cur.getDatabases()
#Execute query
cur.execute("select * from table")
#Return column info from query
print cur.getSchema()
#Fetch table results
for i in cur.fetch():
print i
Я получаю ниже ошибки:
