Spark多字符分隔符写入写入的数据中不可打印的字符

import org.apache.spark.sql.{SparkSession, Row}
import org.apache.spark.sql.types.{StructType, StructField, StringType}

val spark = SparkSession.builder()
  .appName("SparkExample")
  .getOrCreate()

val data = Seq(
  Row("John", "Doe"),
  Row("Jane", "Smith")
)

val schema = StructType(Seq(
  StructField("firstName", StringType, nullable = false),
  StructField("lastName", StringType, nullable = false)
))

val rdd = spark.sparkContext.parallelize(data)
val df = spark.createDataFrame(rdd, schema)

// 使用多字符分隔符进行数据写入
val outputPath = "hdfs://path/to/output"
val delimiter = "abc\tdef"  // 分隔符为"abc\tdef"，其中"\t"表示制表符
df.write
  .option("delimiter", delimiter)
  .csv(outputPath)
