向pyspark Dataframe添加新行

正如bluephantom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 Sparkcontextspark = 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()
