----------------------------------
[~sseth] I assume this should be resolved as a dup of TEZ-2968?
> State transitions do not handle unchecked exceptions

> Key: TEZ-2862
> URL: https://issues.apache.org/jira/browse/TEZ-2862
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.5.0
> Reporter: Siddharth Seth
> Priority: Critical
>
> An unchecked exception such as a NPE (TEZ-2855) goes all the way up to the
> AsyncDispatcher. This causes the AM to exit without unregistering from the RM
> and moving the DAG into an ERROR state.
> Ideally, unchecked exceptions should cause the DAG to error out.
