[jira] [Updated] (SPARK-1647) Prevent data loss when Streaming driver goes down

Tathagata Das updated SPARK-1647:
-

Fix Version/s: (was: 1.1.0)

> Prevent data loss when Streaming driver goes down
> -
>
> Key: SPARK-1647
> URL: https://issues.apache.org/jira/browse/SPARK-1647
> Project: Spark
>  Issue Type: Bug
>  Components: Streaming
>Reporter: Hari Shreedharan
>
> Currently when the driver goes down, any uncheckpointed data is lost from 
> within spark. If the system from which messages are pulled can  replay 
> messages, the data may be available - but for some systems, like Flume this 
> is not the case. 
> Also, all windowing information is lost for windowing functions. 
> We must persist raw data somehow, and be able to replay this data if 
> required. We also must persist windowing information with the data itself.
> This will likely require quite a bit of work to complete and probably will 
> have to be split into several sub-jiras.
