Jason Lowe commented on TEZ-3009:
---------------------------------
I don't see any indication it's fixed in master. From TezChild.run:
{code}
try {
containerTask = getTaskFuture.get();
} catch (ExecutionException e) {
error = true;
Throwable cause = e.getCause();
return new
ContainerExecutionResult(ContainerExecutionResult.ExitStatus.EXECUTION_FAILURE,
cause, "Execution Exception while fetching new work: " +
e.getMessage());
{code}
So the exception can be silently handled unless the return result is inspected.
TezChild.main simply calls the run method and ignores the result.

> If TezChild encounters an error while trying to obtain a task the error will
> be silently handled. This results in a mysterious shutdown of containers
> with no cause.
