Cassandra：身份验证错误...在群集配置中找不到身份验证器

时间：2018-08-07 04:37:44

标签： apache-spark cassandra

我能够从Spark shell访问Cassandra，并使用shell执行该代码，而不会引发任何错误，但是在部署JAR时无法通过spark-submit进行访问。

遇到错误

no authenticator on host /192.168.1.219:9042: Host /192.168.1.219:9042 requires authentication, but no authentication
     

在群集配置中找到

例外：

使用spark cassandra连接器2.3.1版本...

如果不是SparkSession，则在没有身份验证管理器的情况下启动，应使用spark-submit指定用户名和密码。

--conf spark.cassandra.auth.username=<username> \  
--conf spark.cassandra.auth.password=<password>
