spark Could not write all entries

使用 spark 将 dataFrame 储存到 elasticsearch 出现如下报错：

Caused by: org.elasticsearch.hadoop.EsHadoopException: Could not write all entries [1/1] (Maybe ES was overloaded?). Error sample (first [1] error messages):
	rejected execution of org.elasticsearch.transport.TransportService$4@7d5f91de on EsThreadPoolExecutor[bulk, queue capacity = 50, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@3447703a[Running, pool size = 32, active threads = 32, queued tasks = 68, completed tasks = 9151096]]
Bailing out...

这个无法查到定位到报错位置，所以在新建 spark 的时候进行如下配置：

val masterUrl = "local"
val appName = "ttyb"
val sparkConf = new SparkConf()
  .setMaster(masterUrl)
  .setAppName(appName)
  .set("es.nodes", "172.16.14.21")
  .set("es.port", "9200")
  //Bailing out...错误
  .set("es.batch.size.entries", "1")
  //插入失败后无限重复插数据
  .set("es.batch.write.retry.count", "-1")
  //查数据等待时间
  .set("es.batch.write.retry.wait", "100")
val Spark = SparkSession.builder().config(sparkConf).getOrCreate()

得到新的错误：

org.elasticsearch.hadoop.rest.EsHadoopInvalidRequest:
null

报错显示：

ES 负载过高，需要重新修复

本想重启 ES ，发现是机器 磁盘空间已满 ，查错成功
