我们在德鲁伊数据库中有数据，我们需要使用python读取它以进行进一步的分析处理。我正在尝试使用pydruid包阅读德鲁伊数据库。我使用的是python 3.5。但是，当我运行execute语句时，我收到错误：
以下是我正在运行的代码：
*from pydruid.db import connect
conn = connect(host='XXXXXXX', port=8082, path='/druid/v2', scheme='http')
curs = conn.cursor()
curs.execute("""SELECT * FROM wikipedia LIMIT 10""")*
我得到错误：
JSONDecodeError Traceback (most recent call last)
in ()
----> 1 curs.execute("""SELECT * FROM wikipedia LIMIT 10""")
