由于“未找到 id 的搜索上下文”，Spark 任务失败。我尝试了几个选项，例如

spark.es.input.max.docs.per.partition 250

spark.es.scroll.size 100

spark.es.batch.size.bytes 32mb

但任务仍然失败。我们正在使用： Spark 版本：2.3.1，Elasticsearh 集群版本：6.5.4，elasticsearch-spark 版本：6.5.4

任何帮助都将不胜感激。

增加以下参数的值对我有用。

es.scroll.keepalive=120m（默认值为10m）

参考：https ://www.elastic.co/guide/en/elasticsearch/hadoop/current/configuration.html
