二、 问题

pip not found : https://www.pianshen.com/article/50191151479/pip 不能用问题：
python -m pip install --upgrade --force-reinstall pip
3.impyla、impala
在连接hive时，使用impala的方式，使用的是python3.8，发现很多问题，换成python3.6后连接成功，特此记录。
关联包：
six1.16.0
thrift0.11.0
thrift-sasl0.4.3
impyla0.17.0
impala0.2
Cython0.29.28

from impala.dbapi import connect
import pandas as pd

conn = connect(host='192.168.10.10', port=10000, user=None, password=None, database='default', auth_mechanism="PLAIN")
cur = conn.cursor()

cur.execute("select 1")
row = cur.fetchall()
data = []
for i in row:
    data.append(i[0])

#data = cur.fetchall()
#df = pd.Dataframe(data, columns=cols)
#print(df)
