原因：org.apache.spark.SparkException：写入行时任务失败

val sqlContext = new org.apache.spark.sql.SQLContext(sc);

val rdd =

val header = rdd.first()

val rdd1 = rdd.filter(x => x != header)

val rowRDD = rdd1.map(_.split("\\|")).map(p => Row(p(0).trim, 
p(1).trim,p(2).trim,p(3).trim,p(4).trim,p(5).trim,p(6).trim,p(7).trim,p(8).trim,p(9).trim,

val innerStruct = StructType(StructField("rowid", StringType, true)::StructField("s_startdt",

val peopleSchemaRDD = hiveContext.createDataFrame(rowRDD, innerStruct)




peopleSchemaRDD.write.format("orc").mode("overwrite")
.save("/sit/regenv/hdata/DATAFABRIC/reg_tb_prd_dfab/stg_rdm_all_ctry_cd_ver1/ods=2019-12-06")

在以 ORC 格式保存数据帧 peopleSchemaRDD 时，我收到错误“java.lang.ArrayIndexOutOfBoundsException: 3”

我收到此错误原因：org.apache.spark.SparkException：写入行时任务失败

路径没有问题，因为正在创建文件夹但没有数据传入。我用的是spark 1.6.3版本

SQLContext 存在一些问题，您尝试使用 HiveContext。使用下面的配置来解决这个问题：

spark.sql.orc.impl=native

以上是从 Spark-submit 命令的角度提供的。
