Subject [jira] [Commented] (TEZ-14) Support for speculation of slow tasks
Date Wed, 22 Oct 2014 15:32:33 GMT

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.
