Summary: Support some Schedulable variables immutability and access
Key: SPARK-19567
URL: https://issues.apache.org/jira/browse/SPARK-19567
Project: Spark
Issue Type: Improvement
Components: Scheduler
Affects Versions: 2.1.0
Reporter: Eren Avsarogullari
Priority: Minor
Support some Schedulable variables immutability and access
Some Schedulable variables need refactoring for immutability and access modifiers as follows:
- from vars to vals(if there is no requirement): This is important to support immutability
as much as possible.
Sample => Pool: weight, minShare, priority, name and taskSetSchedulingAlgorithm.
- access modifiers: Specially, vars access needs to be restricted from other parts of codebase
to prevent potential side effects. Sample:
Sample => TaskSetManager: tasksSuccessful, totalResultSize, calculatedTasks etc...
