             Summary: Javadoc contains code that is invalid
                 Key: SPARK-20914
                 URL: https://issues.apache.org/jira/browse/SPARK-20914

          Components: Documentation
    Affects Versions: 2.1.1

            Priority: Minor


i was looking over the {link]dataset|https://spark.apache.org/docs/2.1.1/api/java/org/apache/spark/sql/Dataset.html{link} and noticed the code on top that does not make sense in java.

{code}
 // To create Dataset<Row> using SparkSession
   Dataset<Row> people = spark.read().parquet("...");
   Dataset<Row> department = spark.read().parquet("...");

   people.filter("age".gt(30))
     .join(department, people.col("deptId").equalTo(department("id")))
     .groupBy(department.col("name"), "gender")
     .agg(avg(people.col("salary")), max(people.col("age")));
{code}
invalid parts:
*"age".gt(30)
*department("id")
