正如bluephantom”蓝色幽灵”已经说过的那样，工会是要走的路。我只是在回答您的问题，以举一个pyspark示例：
# if not already created automatically, instantiate Sparkcontext
spark = SparkSession.builder.getOrCreate()
columns = ['id', 'dogs', 'cats']
vals = [(1, 2, 0), (2, 0, 1)]
df = spark.createDataFrame(vals, columns)
newRow = spark.createDataFrame([(4,5,7)], columns)
appended = df.union(newRow)
appended.show()
