scala - 错误:找不到:值StructType/StructField/StringType

Question

我在本地计算机2.0版上运行scala。

val schema = StructType(schemaString.split("|^").map(fieldName =>StructField(fieldName, StringType, true)))
<console>:45: error: not found: value StructType
   val schema = StructType(schemaString.split("|^").map(fieldName =>StructField(fieldName, StringType, true)))
                ^
<console>:45: error: not found: value StructField
   val schema = StructType(schemaString.split("|^").map(fieldName => StructField(fieldName, StringType, true)))
                                                                     ^
<console>:45: error: not found: value StringType
   val schema = StructType(schemaString.split("|^").map(fieldName => StructField(fieldName, StringType, true)))
                                                                                            ^

我加载了导入org.apache.spark.sql._，但仍然收到此错误。我缺少任何包裹吗？

Answer 1

import org.apache.spark.sql.types.{StructType, StructField, StringType, IntegerType};

尝试导入
