我怎么才能连接到预装的pyhive呢？

Question

我想用齐柏林的pyhive连接预告片

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

我使用连接函数和正确的参数。

%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)

我怎么才能修好它？

Answer 1

你试过把用户名和密码分开吗？presto.connect(host='xxx', port=xxx, username='xxx', password='xxx')为我工作过。

Answer 2

我的连接看起来是：

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

注意，在我的输入中，端口是一个str，而不是一个int。
