【原创】用python连接thrift Server 去执行sql的问题总汇

 

场景：python和现有产品的结合和应用——python的前瞻性调研

环境：centos7

0、首先确保安装了python和pyhive，下面是连接代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys


from pyhive import hive
from TCLIService.ttypes import TOperationState

def pyhiveexesql(sql):
    cursor = None
    try:
    cursor = hive.connect(host='10.19.12.20', port=10015, username='xxx').cursor()

    cursor.execute(sql, async=True)

    status = cursor.poll().operationState
    while status in (TOperationState.INITIALIZED_STATE, TOperationState.RUNNING_STATE):
        logs = cursor.fetch_logs()
        for message in logs:
        print message
        # If needed, an asynchronous query can be cancelled at any time with:
        # cursor.cancel()
        status = cursor.poll().operationState
    print cursor.fetchall()
    except Exception, e:
        print '%s' % (e.message)
    finally:
        cursor.close()

if __name__ == '__main__':
    pyhiveexesql('SELECT * FROM my_awesome_data LIMIT 10')

问题一：ImportError: No module named sasl

解决：找不到saal就装嘛，执行：sudo pip install sasl，于是爆出第二个问题

问题二：Error：command 'gcc' failed with exit status 1

解决：网上说安装sasl之前有一些前置支撑包，好吧有安装了一些，但还是无动于衷，于是疯狂找了一天终于找到了解决方案：

执行：sudo yum install libffi-devel;sudo yum install libgsasl-devel;sudo yum install libmemcached-devel;

好吧，问题一解决了，但是又爆出问题三：

问题三：ImportError: No module named thrift_sasl

解决方案：sudo yum -y install easy_install; sudo easy_install thrift; sudo pip install thrift_sasl;

好吧问题二和问题三解决了，但是又爆出问题四：

问题四：pyhive.exc.OperationalError: TFetchResultsResp(status=TStatus(errorCode=0, errorMessage=u'Expected state FINISHED, but found ERROR'

具体问题：

[hfb@192 ~]$ python Desktop/pyhive4.py 
Traceback (most recent call last):

    print cursor.fetchall()

解决方案：表不存在，哈哈，这个错误信息不明显啊

完。。。
