有人知道塞纳本生图书馆(https://github.com/cerner/bunsen)将加载fhir r4包并将数据持久化到spark sql数据库？如果有人能给我任何指导或指点，那就太好了。目前我只是想从https://simplifier.net/ukcore. 最终目标是将传入的bundle持久化到一个hive数据库中，以供apachespark集群访问。
尝试加载单个条目包的示例代码是：

Bundles bundles = Bundles.forR4();
URL fileUrl = R4Test.class.getClassLoader().getResource("ukcore/UKCore-AllergyIntolerance-Amoxicillin-Example.json");
JavaRDD bundlesRdd = bundles.loadFromDirectory(spark, fileUrl.toExternalForm(), 200);
Object c = bundlesRdd.collect();
bundles.saveAsDatabase(spark, bundlesRdd, "r4database", "AllergyIntolerance");

上 bundlesRdd.collect() 我收到以下警告：

INFO WholeTextFileRDD: Input split: Paths:/path/to/ukcore/UKCore-AllergyIntolerance-Amoxicillin-Example.json:0+2017
WARN LenientErrorHandler: Unknown element 'meta' found while parsing

WARN LenientErrorHandler: Unknown element 'recordedDate' found while parsing
WARN LenientErrorHandler: Unknown element 'recorder' found while parsing

当你试图 saveAsDatabase() 失败原因：
