Siddharth Seth updated TEZ-1779:
--------------------------------
Target Version/s: 0.6.0
Labels: speculation (was: )
> Handle race condition for failure after success of a leaf vertex task
> ---------------------------------------------------------------------
>
> Key: TEZ-1779
> URL: https://issues.apache.org/jira/browse/TEZ-1779
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Bikas Saha
> Labels: speculation
>
> Currently, a leaf task is not expected to fail after success because tasks
> fail after success only when outputs are reported failed and noone can report
> a leaf vertex output as failed because noone reads it. However, as discussed
> in TEZ-14, there can be a case where 2 attempts are running and 1 succeeds.
> Then the second one is killed but it fails before getting killed. This
> failure would break the cannot fail after success assumption that currently
> is present in the code. Does the leaf vertex need special handling anyways?
