vanzin opened a new pull request #25819: [SPARK-29105][core] Keep driver log file size up to date in HDFS. URL: https://github.com/apache/spark/pull/25819 HDFS doesn't update the file size reported by the NM if you just keep writing to the file; this makes the SHS believe the file is inactive, and so it may delete it after the configured max age for log files. This change uses hsync to keep the log file as up to date as possible when using HDFS. Tested with a SHS configured to aggressively clean up logs; verified a spark-shell session kept updating the log, which was not deleted by the SHS.
