Subject [jira] [Created] (TEZ-2638) Identify and act on hung tasks
Date Thu, 23 Jul 2015 21:18:04 GMT
Bikas Saha created TEZ-2638:
-------------------------------

             Summary: Identify and act on hung tasks
                 Key: TEZ-2638
                 URL: https://issues.apache.org/jira/browse/TEZ-2638
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Bikas Saha


Sometimes tasks can hang/get stuck due to external or user code issues. Speculated versions
of them will also end up hanging. Being able to identify hung tasks (eg no progress on input/outputs,
no cpu) and terminating them with proper error message can provide better user experience.
