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. > Support for speculation of slow tasks > ------------------------------------- > > Key: TEZ-14 > URL: https://issues.apache.org/jira/browse/TEZ-14 > Project: Apache Tez > Issue Type: Improvement > Reporter: Bikas Saha > Assignee: Bikas Saha > Attachments: TEZ-14.1.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
