如何连接到 presto pyhive？

Question

我想在 zeppelin 中使用 pyhive 连接 presto

现在，我关注https://github.com/dropbox/PyHive

我使用连接功能并更正参数。

%python
from pyhive import presto
cursor =  presto.connect(host='localhost',
                port=10000,
                username='id:password').cursor()
cursor.execute('SELECT * FROM table LIMIT 10')

但它不起作用。

Traceback (most recent call last):
  File "/tmp/zeppelin_python-557261260901431465.py", line 278, in <module>
    raise Exception(traceback.format_exc())
Exception: Traceback (most recent call last):
  File "/tmp/zeppelin_python-557261260901431465.py", line 266, in <module>
    exec(code)
  File "<stdin>", line 5, in <module>
  File "/usr/lib/python2.7/dist-packages/pyhive/presto.py", line 206, in execute
    self._process_response(response)
  File "/usr/lib/python2.7/dist-packages/pyhive/presto.py", line 263, in _process_response
    response_json = response.json()
  File "/usr/lib/python2.7/dist-packages/requests/models.py", line 650, in json
    return json.loads(self.content.decode(encoding), **kwargs)
  File "/usr/lib64/python2.7/encodings/utf_32_le.py", line 11, in decode
    return codecs.utf_32_le_decode(input, errors, True)
UnicodeDecodeError: 'utf32' codec can't decode bytes in position 4-7: code point not in range(0x110000)

我该如何解决？

Answer 1

您是否尝试过将用户名和密码分开？

presto.connect(host='xxx', port=xxx, username='xxx', password='xxx')

为我工作。

Answer 2

我的连接看起来像：

presto.connect(host=url, port=port_num, protocol='https', username=user, password=pass)

注意，端口是

str

，而不是我输入的

int

。
