Log document id when MapperParsingException occurs #37658
Description
Elasticsearch version: 5.6 6.x
Indexing a document using the java api may result in a MapperParsingException. When bulk-indexing, the problematic field-name is logged by elasticsearch (log-level has to be set to debug), but not the document-id. Indexing millions of documents it's hard to track down which specific document has the trouble. So, it would be nice to also have the document's id to get straight to the source.
