Marius Soutier commented on SPARK-6613:
---------------------------------------
It's combination of actorStreams and StreamingContext.getOrCreate(). I've
started to update the actorStream example from spark-examples, but it will take
some more time to complete it. I'll post the code here.
> Starting stream from checkpoint causes Streaming tab to throw error
> -------------------------------------------------------------------
>
> Key: SPARK-6613
> URL: https://issues.apache.org/jira/browse/SPARK-6613
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.2.1
> Reporter: Marius Soutier
>
> When continuing my streaming job from a checkpoint, the job runs, but the
> Streaming tab in the standard UI initially no longer works (browser just
> shows HTTP ERROR: 500). Sometimes it gets back to normal after a while, and
> sometimes it stays in this state permanently.
