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.
需要设置.config("spark.debug.maxToStringFields", "100")
SparkSession
.builder()
.master("local[4]")
.appName("report")
.config("spark.debug.maxToStringFields", "100")
.getOrCreate();
