Thanks Gopal. That's a good point to investigate. I guess the container is not reused when disabled auto-reducer in my case is due to that the default timeout for tez is about 10s.

Thank you! Yes - the edge is not used to determine reuse potential. Possibly the patch in https://issues.apache.org/jira/browse/TEZ-3852 might give you a starting point to investigate the conditions when a container is reused. Cheers, Gopal
