Question

我是Spark新手，我们目前正在使用spark-java从Oracle数据库创建orc文件。我能够用

配置连接

sqlContext.read().jdbc(url,table,props)

但是，我无法在属性中找到任何指定trustStore或trustStoreType的方法。有人可以帮助我如何指定这些属性吗？

我已经尝试将属性填充为

 props.put("trustStore", "<PATH_TO_SSO>");
 props.put("trustStoreType", "sso");

但它对我不起作用

UPDATE1：我已经尝试了user8371915的建议，并将sso文件放在我的两个执行器节点中。我仍然得到以下异常（删节版）

Answer 1

首先（Xephi的this answer）信用额度为javax.net.ssl.trustStore和javax.net.ssl.trustStoreType。

第二个问题是每个执行程序节点上都应该可以访问trustStore。无法从驾驶员那里获得它。
