Spark DataFrame groupBy and sort in the descending order (pyspark)

I'm using pyspark(Python 2.7.9/Spark 1.3.1) and have a dataframe GroupObject which I need to filter & sort in the descending order. Trying to achieve it via this piece of code.

group_by_dataframe.count().filter("`count` >= 10").sort('count', ascending=False)

But it throws the following error.

sort() got an unexpected keyword argument 'ascending'

In PySpark 1.3 sort method doesn't take ascending parameter. You can use desc method instead:

from pyspark.sql.functions import col

(group_by_dataframe
    .count()
    .filter("`count` >= 10")
    .sort(col("count").desc()))

or desc function:

from pyspark.sql.functions import desc

(group_by_dataframe
    .count()
    .filter("`count` >= 10")
    .sort(desc("count"))

Both methods can be used with with Spark >= 1.3 (including Spark 2.x).

Use orderBy:

df.orderBy('column_name', ascending=False)

Complete answer:

group_by_dataframe.count().filter("`count` >= 10").orderBy('count', ascending=False)

http://spark.apache.org/docs/2.0.0/api/python/pyspark.sql.html

By far the most convenient way is using this:

df.orderBy(df.column_name.desc())

Doesn't require special imports.

you can use groupBy and orderBy as follows also

dataFrameWay = df.groupBy("firstName").count().withColumnRenamed("count","distinct_name").sort(desc("count"))
