beliefer opened a new pull request #26204: [SPARK-29548][Core] Redirect system print stream to log4j and improve robustness URL: https://github.com/apache/spark/pull/26204 ### What changes were proposed in this pull request? In a production environment, user behavior is highly random and uncertain. For example: Users use `System.out` or `System.err` to print information. But the system print stream may cause some trouble, such as: the disk file is too large. In my production environment, it causes the disk to be full and let [NodeManager] works not fine. A method of threat is to forbid the use of `System.out` or `System.err`. But unfriendly to the users. A better method is to redirecting the system print stream to `Log4j` and Spark can take advantage of `Log4j`'s split log. ### Why are the changes needed? Improve robustness about system `PrintStream`. ### Does this PR introduce any user-facing change? No ### How was this patch tested? Exists UT.
