当我使用JanusGraph 0.2.0文档第35章中的示例时，没关系。但是当我将conf / hadoop-graph / hadoop-load.properties中的spark.master从local [*]更改为spark：//192.168.63.105：7077时，我收到一些警告信息。
JanusGraph 0.2.0文档的第35章中有一条注释： 本章中的示例基于在本地模式下运行Spark。在独立模式下使用Spark或在Yarn或Mesos上运行Spark时，需要进行其他配置。 什么是附加配置？

我的配置文件是conf / janusgraph-hbase-es-test-spark.properties，其内容如下：

我使用的火花版本是spark-2.2.0-bin-hadoop2.7。
我也尝试spark-1.6.0-bin-hadoop2.6，警告信息如下：
