--------------------------------
Summary: More flexible simultaneous execution of execution blocks
Key: TAJO-1708
URL: https://issues.apache.org/jira/browse/TAJO-1708
Project: Tajo
Issue Type: Improvement
Components: Scheduler
Reporter: Jihoon Son
Assignee: Jihoon Son
Fix For: 0.11.0
Currently, an EB can be scheduled only when all child EBs of all sibling EBs
are finished. This limits a lot of opportunities of simultaneous execution of
EBs.
Until now, this is not allowed due to a bug when the number of shuffle
partitions is changed according to the execution order of EBs.
This ticket is to fix that bug and allow to execute an EB as soon as when its
child EBs are finished.
