[GitHub] [helix] jiajunwang opened a new pull request #1930: Fix race condition in scheduler message handling logic.

jiajunwang opened a new pull request #1930:
URL: https://github.com/apache/helix/pull/1930


   ### Issues
   
   - [ ] My PR addresses the following Helix issues and references them in the PR description:
   
   Resolves #1906 #1788
   
   ### Description
   
   - [X] Here are some details about my PR, including screenshots of any UI changes:
   
   This PR aims to fix the race condition that happens during processing scheduler messages. The previous logic which dynamically deletes task partitions in the scheduler message IdealState may cause conflicts and result in inconsistent message status update. Since updating the task partitions is not a necessary step, this PR removes the corresponding logic and simplifies the message handling procedure.
   
   This PR will help to stabilize TestSchedulerMessage.java.
   
   ### Tests
   
   - [X] The following tests are written for this issue:
   
   TestSchedulerMessage
   
   - The following is the result of the "mvn test" command on the appropriate module:
   
   (If CI test fails due to known issue, please specify the issue and test PR locally. Then copy & paste the result of "mvn test" to here.)
   
   ### Changes that Break Backward Compatibility (Optional)
   
   - My PR contains changes that break backward compatibility or previous assumptions for certain methods or API. They include:
   
   (Consider including all behavior changes for public methods or API. Also include these changes in merge description so that other developers are aware of these changes. This allows them to make relevant code changes in feature branches accounting for the new method/API behavior.)
   
   ### Documentation (Optional)
   
   - In case of new functionality, my PR adds documentation in the following wiki page:
   
   (Link the GitHub wiki you added)
   
   ### Commits
   
   - My commits all reference appropriate Apache Helix GitHub issues in their subject lines. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)":
     1. Subject is separated from body by a blank line
     1. Subject is limited to 50 characters (not including Jira issue reference)
     1. Subject does not end with a period
     1. Subject uses the imperative mood ("add", not "adding")
     1. Body wraps at 72 characters
     1. Body explains "what" and "why", not "how"
   
   ### Code Quality
   
   - My diff has been formatted using helix-style.xml 
   (helix-style-intellij.xml if IntelliJ IDE is used)
