Tathagata Das updated SPARK-1386:
---------------------------------
Priority: Blocker (was: Major)
> Spark Streaming UI
> ------------------
>
> Key: SPARK-1386
> URL: https://issues.apache.org/jira/browse/SPARK-1386
> Project: Spark
> Issue Type: New Feature
> Components: Streaming
> Reporter: Tathagata Das
> Priority: Blocker
>
> When debugging Spark Streaming applications it is necessary to monitor
> certain metrics that are not shown in the Spark application UI. For example,
> what is average processing time of batches? What is the scheduling delay? Is
> the system able to process as fast as it is receiving data? How many records
> I am receiving through my receivers?
> While the StreamingListener interface introduced in the 0.9 provided some of
> this information, it could only be accessed programmatically. A UI that shows
> information specific to the streaming applications is necessary for easier
> debugging.
