Kuhu Shukla updated TEZ-1259:
-----------------------------
Attachment: TEZ-1259.001.patch
[~sseth], this may be a slightly different but related problem where vertices
that are re-run due to retroactive failures do not show up on the UI as Running
and in cases where we did hit TEZ-3758, the vertex state showed succeeded
instead of running. This patch *adds* log for VERTEX_STARTED event when this
happens. I can open a different JIRA if you think this issue is unrelated.
Appreciate any comments on this. Will leave this JIRA open until we decide
which way to go.
> Vertex should move to RUNNING state without generating an extra VERTEX_START

> Currently, we end up generating a VERTEX_START event targeted at the same
> vertex when a vertex is ready to start. Instead, the Vertex can directly move
> to started state - which prevents unnecessary event queueing.
