[~bikassaha],
Merge Join is not a simple disjointed DAG. The DAGs need sequential
execution (in order). exec commands inside pig script is another case.
bq. We could add a config that makes the session fail when a DAG in that
session fails.
Sounds good. But I don't think that will work with our stop_on_failure=no
feature. i.e if one of the disjoint DAGs fail, continue processing others. We
have not implemented that in Tez yet. So it would be better to have a config
to report AM status on session termination (shutdown or timeout) as killed or
failed if there are killed or failed DAGs.
