Bikas Saha commented on TEZ-1247:
---------------------------------
Can verify() be called without calling processDAGEdges()? If not, then can
verify be called multiple times if processDAGEdges() can only be called once?
bq. otherwise even the dry-run still has the issue. What do you think ?
What are the issues? From what I see, user runs the app on the client just like
a normal case to submit the job. Internally, job is not submitted. Only the
compilation is carried out and the results (dot plot + PB DAGplan) are written
out for debugging. There is no difference between a dry-run and a real run
except that the real run makes externally changes (like uploading jars and
submitting the DAG).
