我正在尝试使用pyhs2访问配置单元。我尝试了以下代码：

示例.pyimport pyhs2

conn = pyhs2.connect(host='localhost', port=10000,authMechanism=None, user=None, password=None,database='default')

with conn.cursor() as cur:

cur.execute("select * from table")

for i in cur.fetch():

print i

我得到以下错误：Traceback (most recent call last):

File "example.py", line 2, in conn = pyhs2.connect(host='localhost', port=10000,authMechanism=None, user=None, password=None,database='default')

File "build/bdist.linux-x86_64/egg/thrift/transport/TSocket.py", line 101, in open

thrift.transport.TTransport.TTransportException: Could not connect to localhost:10000

当我尝试使用hive-utils时，我得到了准确的错误。我已经检查过sasl的安装。我需要更改配置单元中的hive-site.xml吗？如果是，我需要在哪里创建它？我错过了什么吗？
