-----------------------------------
Summary: Add hold mode for the LiveListenerBus
Key: SPARK-21560
URL: https://issues.apache.org/jira/browse/SPARK-21560
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.2.0, 2.1.0
Reporter: Li Yuanjian
As the comments in SPARK-18838, we also face the same problem about critical
events dropped while the event queue is full.
There's no doubt that improving the performance of the processing thread is
important, whether the solution is multithreading or any others like
SPARK-20776, but maybe we still need the hold strategy when the event queue is
full, and restart after some room released. The hold strategy open or not and
the empty rate should both configurable.
