-------------------------------
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.
