Tathagata Das updated SPARK-1331:
---------------------------------
Priority: Blocker (was: Critical)
> Graceful shutdown of Spark Streaming computation
> ------------------------------------------------
>
> Key: SPARK-1331
> URL: https://issues.apache.org/jira/browse/SPARK-1331
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 0.9.0
> Reporter: Tathagata Das
> Assignee: Tathagata Das
> Priority: Blocker
>
> Current version of StreamingContext.stop() directly kills all the data
> receivers (NetworkReceiver) without waiting for the data already received to
> be persisted and processed. Fixing this requires the following.
> 1. Each receiver, when it gets a stop signal from the driver, should stop
> receiving, and then wait for all the received data to have been persisted and
> reported to the driver.
> 2. The driver, after stopping all the receivers, should wait for all the
> received to be processed.
