[jira] [Comment Edited] (SPARK-12786) Actor demo does not
demonstrate usable code
[ https://issues.apache.org/jira/browse/SPARK-12786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15101918#comment-15101918 ]

---------------------------------------------------------------
Yeah, exactly. Because of the use of {{AkkaUtil}} the settings needed to create a minimal actor system that can communicate with the actor stream is buried in the Spark code.
I believe the change at https://github.com/apache/spark/pull/10744/files#diff-690ab3eacd0a42fe7bee1d29c5910ffdR111 will resolve this issue.
On a side note, are there plans to include classes to use actors as a DStream output as well?

> Key: SPARK-12786
> URL: https://issues.apache.org/jira/browse/SPARK-12786
> Project: Spark
> Issue Type: Documentation
> Components: Streaming
> Affects Versions: 1.5.2, 1.6.0
> Reporter: Brian London
> Priority: Minor
>
> The ActorWordCount demo doesn't show how to set up an actor based dstream in a way that can be used.
> The demo relies on the {{AkkaUtils}} object, which is marked private[spark]. Thus the code presented will not compile unless users declare their code to be in the org.apache.spark package.
> Demo is located at https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/examples/streaming/ActorWordCount.scala
