Bikas Saha commented on TEZ-1597:
---------------------------------

lgtm. please run all tests before committing.
This log could go once when we set this up (and also include a log for vertices being ignored) in onVertexStarted()?

           //do not schedule tasks until a task from source task is complete
+          LOG.info("Wait scheduling tasks in " + getContext().getVertexName()
+              + " until a task completes in " + entry.getKey());

> ImmediateStartVertexManager would keep waiting for source completed event from the vertex with 0 task and would get into hung state.
