Apache spark spark-避免冗长架构的堆栈溢出错误

我有一个spark代码，它定义了一个包含950多列的模式。它有点像下面

 val cust_schema = new StructType()
    .add(StructField("COL_1",DecimalType(16,0)))
    .add(StructField("COL_2",StringType))
    .add(StructField("COL_3",DecimalType(6,0)))
    .add(StructField("COL_4",StringType))
    .add(StructField("COL_5",StringType))
    .add(StructField("COL_6",DecimalType(4,0)))
    . . . . 
    . . . . 

    .add(StructField("COL_950",DecimalType(4,0)))
    .add(StructField("COL_951",DecimalType(4,0)))
    .add(StructField("COL_952",StringType))

我编译这个时出错了

当我将列数减少到500+时，代码将编译。。但这并不总是一致的。编译器有时会抛出错误，即使看起来像scala编译器问题。 您可以尝试使用Seq base构造函数而不是链调用

val cust_schema = StructType(Seq(
  StructField("COL_1",DecimalType(16,0)),
  StructField("COL_2",DecimalType(16,0)),
  ...
  StructField("COL_952",DecimalType(16,0))
))

我已经导入了超过2000列的CSV文件，并修改了它们的模式。我从来没有这个问题。尽管我没有像您这样添加模式。你确定这是一个火花问题吗？我看到您得到了

ServerException

。请看这个：@Nikhil-让我也试试..修复了示例代码。我添加了“）”来关闭StructField”（“。它在本地编译：import org.apache.spark.sql.types.\uObject A{val seq=seq（StructField（“COL_1”，DecimalType（16,0）），StructField（“COL_1”，DecimalType（16,0）））val cust_schema=StructType（seq）}抱歉，我的意思是..尝试了您在这里提到的模式..并得到了与原始帖子中相同的错误..我增加了堆，正如在其他一些链接中提到的，并且使用

StrucType（Seq（…））

它现在可以工作了。。多谢各位
