Uroš Bojanić created SPARK-58922:
------------------------------------
Summary: Extract a null/empty MDC-array check in SparkLogger
Key: SPARK-58922
URL: https://issues.apache.org/jira/browse/SPARK-58922
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 4.3.0
Reporter: Uroš Bojanić
SparkLogger duplicates the check 'mdcs == null || mdcs.length == 0' across six
logging methods (the MDC-varargs error/warn/info overloads). This extracts a
private isNullOrEmpty(MDC[]) helper and routes the six call sites through it.
No behavior change.
