> Key: SPARK-55016
> URL: https://issues.apache.org/jira/browse/SPARK-55016
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.0.1, 3.5.7, 4.1.1
> Reporter: L. C. Hsieh
> Priority: Major
> Labels: pull-request-available
>
> There is a potential stack overflow issue that can occur when
> SQLConf.get.getConf() is called during SparkSession's sessionState
> initialization. The problem happens when:
> SparkSession becomes active via setDefaultAndActiveSession
> sessionState lazy val starts initializing (not yet complete)
> During initialization, code calls SQLConf.get.getConf()
> confGetter tries to access sessionState.conf
> This creates a recursive loop because sessionState is still initializing
