Question

我安装了一个带有spark运行的DSE 4.5。我需要一些帮助来传递来自Spark Shell的cassandra集群的用户名/密码。

我已将这些属性添加到conf / spark-default.conf文件

dse spark

使用

启动我的火花壳

com.datastax.driver.core.exceptions.AuthenticationException: Authentication error on host /11.111.11.11:9042: Host /11.111.11.11:9042 requires authentication, but no authenticator found in Cluster configuration

    at com.datastax.driver.core.ControlConnection.connect(ControlConnection.java:79)
    at com.datastax.driver.core.Cluster$Manager.init(Cluster.java:1104)

但是当我尝试sc.cassandraTable

时仍然看到错误

dse spark -Dcassandra.username=user -Dcassandra.password=pass

Answer 1

看起来你可以执行这个命令

def test_view(request, format=None):
    service = UserService()
    service.to_something()
    return Response( status=status.HTTP_200_OK )
