我正在尝试将火花数据帧写入Elasticsearch，如下所示：
Py4JJavaError: An error occurred while calling o50.save.:
org.apache.spark.SparkException: Job aborted due to stage failure:
Task 0 in stage 3.0 failed 1 times, most recent failure: Lost task 0.0
in stage 3.0 (TID 8, localhost, executor driver):

nodes with HTTP-enabled available; node discovery is disabled and none

不幸的是，我收到以下错误：
sudo PYSPARK_DRIVER_PYTHON=jupyter-notebook $SPARK_HOME/bin/pyspark --packages org.elasticsearch:elasticsearch-spark-20_2.11:5.3.1 --conf spark.es.nodes="52.XXX.XX.XX" --conf spark.es.port="XXX" --conf spark.es.nodes.discovery=false --conf spark.es.net.http.auth.user="user" --conf spark.es.net.http.auth.pass="password"
我用：
spark = 2.1.0 scala = 2.11 elasticsearch = 2.4.5 Jupyter笔记本
以及以下命令：
Py4JJavaError: An error occurred while calling o50.save.:
org.apache.spark.SparkException: Job aborted due to stage failure:

使用spark.es.nodes.discovery = true时，我收到错误：
fromDraft(Draft draft) {
Object.assign(this, draft);
this.info = new Info();
this.info.value = draft.summary;
}
有人可以帮忙吗？
