Till Rohrmann created FLINK-7866:
------------------------------------
Summary: Weigh list of preferred locations for scheduling
Key: FLINK-7866
URL: https://issues.apache.org/jira/browse/FLINK-7866
Project: Flink
Issue Type: Improvement
Components: Scheduler
Affects Versions: 1.3.2, 1.4.0
Reporter: Till Rohrmann
Fix For: 1.5.0
[~sihuazhou] proposed to not only use the list of preferred locations to decide
where to schedule a task, but to also weigh the list according to how often a
location appeared and then select the location based on the weight. That way,
we would obtain better locality in some cases.
Example:
Preferred locations list: {{{location1, location2, location2}}}
Weighted preferred locations list {{{ (location2 , 2), (location1, 1)}}}
