新的HiveConf()不会加载hive-site.xml

我想从我的hadoop ToolRunner类中的hive-site.xml中访问值(即获取hive委托令牌)。

但是当我执行new HiveConf()new HiveConf(configuration, HiveConf.class)时,创建的HiveConf仅包含默认设置,而没有hive-site.xml中的任何设置

我发现提到解决方案应该是将/ etc / hive / conf添加到hadoop-env.sh中的HADOOP_CLASSPATH中,但这不能解决配置值的加载问题,并在尝试获取时导致异常JDBC HiveConnection。

几乎似乎在类路径上需要更多配置单元代码,但缺少。

找出HiveServer2地址和其他设置的正确方法是什么?
