This PR aims to lower the minimum limit of
spark.eventLog.rolling.maxFileSizefrom10MiBto2MiBat Apache Spark 4.1.0 while keeping the default (128MiB).Why are the changes needed?
spark.eventLog.rolling.maxFileSizehas10MiBas the lower bound limit since Apache Spark 3.0.0.By reducing the lower bound to
2MiB, we can allow Spark jobs to write small log files more frequently and faster without waiting for10MiB. This is helpful some slow(large micro-batch period) or low-traffic streaming jobs. The users will set a proper value for their jobs.Does this PR introduce any user-facing change?
There is no behavior change for the existing jobs. This only extends the range of configuration values for a user who wants to have lower values.
