----------------------------------
Summary: QM should collect Task metrics
Key: TAJO-1698
URL: https://issues.apache.org/jira/browse/TAJO-1698
Project: Tajo
Issue Type: Sub-task
Components: Metrics, QueryMaster
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.11.0
Each task can collect various metrics, like input data volume, output data
volume, shuffle data volume, and so on. In this issue, I'll add Task metrics
and improve QM to collect Task metrics and keep aggregated values of all task
metrics. Then, I'll improve TajoMaster to keep the final aggregated metrics for
each query.
