---------------------------------
Summary: Eliminate local data transmission during repartition
phases
Key: TAJO-222
URL: https://issues.apache.org/jira/browse/TAJO-222
Project: Tajo
Issue Type: Improvement
Components: repartitioning
Reporter: Hyunsik Choi
During a repartition phase, each worker pulls intermediate of completed tasks
of one or more child execution blocks. However, a worker pulls the intermediate
data completed at the same worker via HTTP. This causes unnecessary read/write
overheads on disk. We should eliminate this overhead.
