Apache Spark在Jersey依赖项注入方面表现不佳

我正在尝试使用该com.github.sps.metrics.metrics-opentsdb库将指标从我的Spark作业记录到我的OpenTSDB服务器。我遇到一个问题，在处理EncodingFilters的球衣代码中，我得到了一个奇怪的NPE。

这是我得到的例外：

ERROR OpenTsdb: send to opentsdb endpoint failed

我查看了EncodingFilter.class中的代码，看到我失败的行是这样的：

List<ContentEncoder> encoders = serviceLocator.getAllServices(ContentEncoder.class);

在类中，我看到未实例化serviceLocator，而是在类顶部看到了以下行：

@Inject
private ServiceLocator serviceLocator;

我最初以为这可能是一个不好的依赖关系，所以我检查my mvn dependency:tree并确保cxf和jersey项目的所有版本都匹配，所以我不认为这是问题所在。现在，我认为它与Apache Spark特别相关，我认为这是因为我有一个使用相同metrics-opentsdb库的单独应用程序，而我从未见过上述异常，因此在我的其他应用程序中一切正常。

那么，有谁知道球衣依赖注入和火花是怎么回事？有没有人处理过同样的问题并解决了？这个问题是否还存在？
