con = cql.connect(host="127.0.0.1",port=9160,keyspace="my_keyspace",cql_version='3.0.0')

cql.apivalues.ProgrammingError:错误请求:您尚未登录

我是第一次来cassandra，请让我知道我在这里做错了什么。

Answer 1

假设您使用的是https://pypi.python.org/pypi/cql，如果您转到主页，它会显示这是已弃用的https://code.google.com/archive/a/apache-extras.org/p/cassandra-dbapi2

我推荐使用cassandra-driver https://datastax.github.io/python-driver

Answer 2

去\var\log\cassandra，在那里你必须找到system.log文件。在那里您应该会看到一个错误
