I am pleased to announce the release of MR3 0.6. New key features are: - In Hive on Kubernetes, DAGAppMaster can run in its own Pod. - MR3-UI requires only Timeline Server. - Hive on MR3 is much more stable because it supports memory monitoring when loading hash tables for Map-side join.

The result can be found in a new article: https://mr3.postech.ac.kr/blog/2019/03/22/performance-evaluation-0.6/ I hope you enjoy reading the article. --- Sungwoo
