erenavsarogullari b7be05a203 [SPARK-19567][CORE][SCHEDULER] Support some Schedulable variables immutability and access ... ## What changes were proposed in this pull request? Some `Schedulable` Entities(`Pool` and `TaskSetManager`) variables need refactoring for _immutability_ and _access modifiers_ levels as follows: - From `var` to `val` (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, `var`s access needs to be restricted from other parts of codebase to prevent potential side effects. - `TaskSetManager`: `tasksSuccessful`, `totalResultSize`, `calculatedTasks` etc... This PR is related with #15604 and has been created seperatedly to keep patch content as isolated and to help the reviewers. ## How was this patch tested? Added new UTs and existing UT coverage. Author: erenavsarogullari <erenavsarogullari@gmail.com> Closes #16905 from erenavsarogullari/SPARK-19567.		2017-03-23 17:20:52 -07:00
