Saurabh Santhosh commented on SPARK-6988:
-----------------------------------------
Hey,
Can someone update the Spark documentation as well. (For correct usage of Data
Frames)
https://spark.apache.org/docs/latest/sql-programming-guide.html
Eg :
DataFrame teenagers = sqlContext.sql("SELECT name FROM parquetFile WHERE age >=
13 AND age <= 19");
List<String> teenagerNames = teenagers.map(new Function<Row, String>() {
public String call(Row row) {
return "Name: " + row.getString(0);
}
}).collect();
to change teenagers.map to teenagers.javaRDD().map
> Fix Spark SQL documentation for 1.3.x
