Chen He commented on TEZ-14:
----------------------------
Hi, [~bikassaha], it is nice work. I have a question. Since there are different
types of DAGs and various types of vertices in a single DAG, customized
speculator may be good to fit different types of jobs. Do we need to provide a
parameter that can allow user to use their own speculator? Please neglect if it
is incorrect.
