Spark 运行警告：spark.debug.maxToStri

spark运行报错

Truncated the string representation of a plan since it was too large. This behavior can be adjusted by setting 'spark.debug.maxToStringFields' in SparkEnv.conf.

可以设置一个参数.config("spark.debug.maxToStringFields", "100")

SparkSession
        .builder()
        .master("local[*]")
        .appName("report")
        .config("spark.debug.maxToStringFields", "100")
        .getOrCreate();
