Option 2. Using withColumnRenamed, notice that this method allows you to “overwrite” the same column. For Python3, replace xrange with range. from functools import reduce oldColumns = data.schema.names newColumns = ["name", "age"] df = reduce(lambda data, idx: data.withColumnRenamed(oldColumns[idx], newColumns[idx]), xrange(len(oldColumns)), data) df.printSchema() df.show()
Option 3. using alias, in Scala you can also use as. from pyspark.sql.functions import col data = data.select(col("Name").alias("name"), col("askdaosdka").alias("age")) data.show() # Output #+-------+---+ #| name|age| #+-------+---+ #|Alberto| 2| #| Dakota| 2| #+-------+---+
Option 4. Using sqlContext.sql, which lets you use SQL queries on DataFrames registered as tables. sqlContext.registerDataFrameAsTable(data, "myTable") df2 = sqlContext.sql("SELECT Name AS name, askdaosdka as age from myTable") df2.show() # Output #+-------+---+ #| name|age| #+-------+---+ #|Alberto| 2| #| Dakota| 2| #+-------+---+
