Lev updated SPARK-18970:
------------------------
Summary: FileSource failure during refresh doesn't cause an application to
fail, but stops further processing (was: FileSource filure during refresh
doesn't cause an application to fail, but stops further processing)

> Key: SPARK-18970
> URL: https://issues.apache.org/jira/browse/SPARK-18970
> Project: Spark
> Issue Type: Bug
> Components: SQL, Structured Streaming
> Affects Versions: 2.0.0
> Reporter: Lev
>
> Spark streaming application uses S3 files as streaming sources. After running
> for several day processing stopped even though an application continued to
> run.
> Stack trace:
> java.io.FileNotFoundException: No such file or directory

> I believe 2 things should (or can) be fixed:
> 1. Application should fail in case of such an error.
> 2. Allow application to ignore such failure, since there is a chance that
> during next refresh the error will not resurface. (In my case I believe an
> error was cased by S3 cleaning the bucket exactly at the same moment when
> refresh was running)
> My code to create streaming processing looks as the following:
> val cq = sqlContext.readStream
> .format("json")
> .schema(struct)
> .load(s"input")
> .writeStream
> .option("checkpointLocation", s"checkpoints")
> .foreach(new ForeachWriter[Row] {...})
> .trigger(ProcessingTime("10 seconds")).start()
>
> cq.awaitTermination()
