I'm attempting to write data to elasticsearch using pyspark. I can successfully write using the "saveAsNewAPIHadoopFile" api for most cases, however, when one of the json objects is a list, it throws an error:
`SparkException: Data of type java.util.ArrayList cannot be used`
ES can ingest lists via other means, and it is a bit cumbersome to transform my list to another state. Any advice would be useful. For refference, I am using
ElasticSearch 1.7.3
Spark 1.5.0-cdh5.5.1,
Hadoop 2.6.0-cdh5.5.1
ES-Hadoop connector: elasticsearch-hadoop-2.2.0.jar
