lining updated FLINK-14717:
---------------------------
Description:
*Current*
The job's exceptions just show current attempt’s exceptions in web UI.
If the job failovers, we couldn't see any prior attempts' exceptions.
*Proposal*
We could use executionVertex.getPriorExecutionAttempt to get prior attempt in
JobExceptionsHandler.
{code:java}
for (int i = task.getAttemptNumber() - 1; i >= 0; i--) {
task = executionVertex.getPriorExecutionAttempt(i);
}
{code}
was:
Now JobExceptionsHandler just shows current attempt exceptions. If job
failovers, there may some prior attempts. But they didn't show in
JobExceptionsHandler. We could use executionVertex.getPriorExecutionAttempt to
get prior attempt.
{code:java}
for (int i = task.getAttemptNumber() - 1; i >= 0; i--) {
task = executionVertex.getPriorExecutionAttempt(i);
}
{code}
> JobExceptionsHandler show exceptions of prior attempts
