--------------------------------------
Summary: pyspark.DStream top method
Key: SPARK-8827
URL: https://issues.apache.org/jira/browse/SPARK-8827
Project: Spark
Issue Type: Improvement
Components: PySpark, Streaming
Reporter: Emanuele Cesena
Priority: Minor
Is there a reason for not having DStream.top?
Any issues with the following definition?
```
def topPartition(partition):
return sorted(partition, key=lambda p: p[1], reverse=True)[:10]
def top(counts):
return counts.transform(lambda rdd: rdd.mapPartitions(topPartition)
.sortBy(lambda p: p[1],ascending=False))
```
