Question

在尝试连接到配置单元之前，是否有任何人遇到此错误。

使用的示例代码（https://github.com/telefonicaid/fiware-cygnus/blob/master/cygnus-ngsi/resources/hiveclients/python/hiveserver2-client.py）：

import sys
import pyhs2
from pyhs2.error import Pyhs2Exception

# get the input parameters
if len(sys.argv) != 6:
    print 'Usage: python hiveserver2-client.py <hive_host> <hive_port> <db_name> <hadoop_user> <hadoop_password>'
    sys.exit()

hiveHost = sys.argv[1]
hivePort = sys.argv[2]
dbName = sys.argv[3]
hadoopUser = sys.argv[4]
hadoopPassword = sys.argv[5]

# do the connection
with pyhs2.connect(host=hiveHost,
                   port=hivePort,
                   authMechanism="PLAIN",
                   user=hadoopUser,
                   password=hadoopPassword,
                   database=dbName) as conn:
    # get a client
    with conn.cursor() as client:
        # create a loop attending HiveQL queries
        while (1):
            query = raw_input('remotehive> ')

            try:
                if not query:
                    continue

                if query == 'exit':
                    sys.exit()

                # execute the query
                client.execute(query)

                # get the content
                for row in client.fetch():
                    print row

            except Pyhs2Exception, ex:
                print ex.errorMessage

显示错误：

你可以张贴你的代码吗？这看起来像某些auth机制或发送的凭据不是有效的。

根据您的设置

authMechanism= can be "PLAIN" or "KERBEROS"。

通过以下方式连接到配置单元时出现套接字错误：hiveserver2-client.py
