Subject [jira] [Commented] (SPARK-22936) providing HttpStreamSource and HttpStreamSink
Date Tue, 02 Jan 2018 15:03:00 GMT

Sean Owen commented on SPARK-22936:
-----------------------------------

I think this can and should start as you have started it, as an external project. If there's
clear demand, it could be moved into the project itself later. Right now people can just add
your artifact and use it with no problem right?

> Hi, in my project I completed a spark-http-stream, which is now available on https://github.com/bluejoe2008/spark-http-stream.
I am thinking if it is useful to others and is ok to be integrated as a part of Spark.
> spark-http-stream transfers Spark structured stream over HTTP protocol. Unlike tcp streams,
Kafka streams and HDFS file streams, http streams often flow across distributed big data centers
on the Web. This feature is very helpful to build global data processing pipelines across
different data centers (scientific research institutes, for example) who own separated data
sets.
> The following code shows how to load messages from a HttpStreamSource:
> ```
> val lines = spark.readStream.format(classOf[HttpStreamSourceProvider].getName)
> 	.option("httpServletUrl", "http://localhost:8080/xxxx")
> 	.option("topic", "topic-1");
> 	.option("includesTimestamp", "true")
> 	.load();
> ```
