-----------------------------------

             Summary: Tail method for spark DataFrame
                 Key: SPARK-26433
                 URL: https://issues.apache.org/jira/browse/SPARK-26433
             Project: Spark
          Issue Type: New Feature
          Components: PySpark
    Affects Versions: 2.4.0
            Reporter: Jan Gorecki


There is a head method for spark dataframes which work fine but there doesn't seems to be tail method.

```
>>> ans                                                                         
DataFrame[v1: bigint]                                                           
>>> ans.head(3)                                                                
[Row(v1=299443), Row(v1=299493), Row(v1=300751)]
>>> ans.tail(3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/jan/git/db-benchmark/spark/py-spark/lib/python3.6/site-packages/py
spark/sql/dataframe.py", line 1300, in __getattr__
    "'%s' object has no attribute '%s'" % (self.__class__.__name__, name))
AttributeError: 'DataFrame' object has no attribute 'tail'
```
I would like to feature request Tail method for spark dataframe
