Bikas Saha created TEZ-2720:
-------------------------------
Summary: Task user code exceptions may show up as
TaskTerminationCause.FRAMEWORK_ERROR
Key: TEZ-2720
URL: https://issues.apache.org/jira/browse/TEZ-2720
Project: Apache Tez
Issue Type: Bug
Reporter: Bikas Saha
The main run() method ends up calling
{code} private void sendFailure(Throwable t, String message) throws
IOException, TezException {
if (!fatalErrorSent.getAndSet(true)) {
task.setFatalError(t, message);
task.setFrameworkCounters();
try {
taskReporter.taskFailed(task.getTaskAttemptID(), t, message,
null);{code}
The last null gives no indication of the source of the failure. This ends up
sending the task failed event with the sourceMeta as SYSTEM.
{code} TezEvent taskAttemptFailedEvent = new TezEvent(new
TaskAttemptFailedEvent(diagnostics),
srcMeta == null ? updateEventMetadata : srcMeta);
return !heartbeat(Lists.newArrayList(statusUpdateEvent,
taskAttemptFailedEvent)).shouldDie;
{code}
In the AM that ends up marking the attempt failure as FRAMEWORK_ERROR instead
of APPLICATION_ERROR.
