Conda 安装Jupyter:使用Pyhive(Kerberos)

安装基本环境

conda create -n bigdata python=3.10

conda activate bigdata

conda install -y pandas numpy pyhive

yum install gcc-c++ python-devel.x86_64 cyrus-sasl-devel.x86_64

pip install sasl

Jupyter Notebook

安装jupyter notebook配置自动提示

复制代码
conda install nb_conda_kernels

配置jupyter,添加密码,允许root,设置启动目录

环境配置-为linux服务器配置可以远程访问的Jupyter - 知乎 (zhihu.com)

jupyter notebook启动,以下报错可忽略

AttributeError: 'NotebookApp' object has no attribute 'io_loop'

PyHive连接开启Kerberos的Hive

jupyter notebook部署的服务器为集群已配置Kerberos认证的服务器,否则需要配置客户端认证

python 复制代码
from pyhive import hive
import pandas as pd
import numpy as np
import time

def func_time(func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        result = func(*args, **kwargs)
        end_time = time.time()

        execution_time = end_time - start_time
        print(f"函数 {func.__name__} 的执行时间为:{execution_time} 秒")

        return result

    return wrapper

        self.cursor = self.conn.cursor()
        return self

    def query(self, sql):
        self.cursor.execute(sql)
        # 将查询结果读取到 DataFrame
        df = pd.DataFrame(self.cursor.fetchall())
        # 设置 DataFrame 列名
        df.columns = [desc[0] for desc in self.cursor.description]
        return df

    def __exit__(self, exc_type, exc_val, exc_tb):
        # 关闭连接
        self.conn.close()
