[jira] [Created] (SPARK-35136) Remove initial null value of LiveStage.info

Sander Goos created SPARK-35136:
-----------------------------------

             Summary: Remove initial null value of LiveStage.info
                 Key: SPARK-35136
                 URL: https://issues.apache.org/jira/browse/SPARK-35136
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 3.1.1
            Reporter: Sander Goos


The `AppStatusListener.getOrCreateStage` method creates a LiveStage object with the `info` field set to null and right after that set it to a specific StageInfo object. This can lead to a race condition when the `livestages` are read in between those calls. This could then lead to a null pointer exception in, for instance: `activeStages`.
