> Invoke task failure callbacks before calling outputstream.close()
> -----------------------------------------------------------------
>
> Key: SPARK-13601
> URL: https://issues.apache.org/jira/browse/SPARK-13601
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Davies Liu
> Assignee: Davies Liu
>
> We need to submit another PR against Spark to call the task failure callbacks
> before Spark calls the close function on various output streams.
> For example, we need to intercept an exception and call
> TaskContext.markTaskFailed before calling close in the following code (in
> PairRDDFunctions.scala):
> {code}
> Utils.tryWithSafeFinally {
> while (iter.hasNext) {
> val record = iter.next()
> writer.write(record._1.asInstanceOf[AnyRef],
> record._2.asInstanceOf[AnyRef])
> // Update bytes written metric every few records
> maybeUpdateOutputMetrics(outputMetricsAndBytesWrittenCallback,
> recordsWritten)
> recordsWritten += 1
> }
> } {
> writer.close()
> }
> {code}
> Changes to Spark should include unit tests to make sure this always work in
> the future.
