我编写了一个 pyspark 脚本,它读取两个 json 文件,coGroup
并将结果发送到 elasticsearch 集群;当我在本地运行它时,一切(大部分)都按预期工作,我下载了和类的elasticsearch-hadoop
jar 文件,然后使用参数使用 pyspark 运行我的作业,我可以看到我的 elasticsearch 集群中出现的文档。org.elasticsearch.hadoop.mr.EsOutputFormat
org.elasticsearch.hadoop.mr.LinkedMapWritable
--jars
但是,当我尝试在 spark 集群上运行它时,出现此错误:

这对我来说似乎很清楚:elasticsearch-hadoop
工人无法使用罐子;所以问题是:我如何将它与我的应用程序一起发送?我可以使用sc.addPyFile
python 依赖项,但它不适用于 jars,并且使用的--jars
参数spark-submit
也无济于事。
