我正在使用Nutch 1.14并试图将一个小的网络爬行索引到ES v5.3.0并且我一直收到此错误:

我已经完成了this,我仍然得到错误...
更新 - 好的,我已经取得了进展。索引似乎现在正常工作 - 没有更多的错误。但是,当我去看看使用_stats通过Kibana检查文件数时,我得到0当Nutch告诉我这个:
Segment dir is complete: crawl/segments/20180830115119.

我假设这意味着ES被发送9个文件用于索引?
我使用了带有nutch 1.14的Elasticsearch 6.0,它就像一个魅力,我使用了带有端口9200的indexer-elastic-rest插件,我附上了我的nutch-site.xml作为参考。
