---------------------------------
ok.
> The log about driver should support rolling like executor
> ---------------------------------------------------------
>
> Key: SPARK-19829
> URL: https://issues.apache.org/jira/browse/SPARK-19829
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: hustfxj
> Priority: Minor
>
> We should rollback the log of the driver , or the log maybe large！！！
> {code:title=DriverRunner.java|borderStyle=solid}
> // modify the runDriver
> private def runDriver(builder: ProcessBuilder, baseDir: File, supervise:
> Boolean): Int = {
> builder.directory(baseDir)
> def initialize(process: Process): Unit = {
> // Redirect stdout and stderr to files------ the old code
> // val stdout = new File(baseDir, "stdout")
> // CommandUtils.redirectStream(process.getInputStream, stdout)
> //
> // val stderr = new File(baseDir, "stderr")
> // val formattedCommand = builder.command.asScala.mkString("\"", "\"
> \"", "\"")
> // val header = "Launch Command: %s\n%s\n\n".format(formattedCommand,
> "=" * 40)
> // Files.append(header, stderr, StandardCharsets.UTF_8)
> // CommandUtils.redirectStream(process.getErrorStream, stderr)
> // Redirect its stdout and stderr to files---------support rolling
> val stdout = new File(baseDir, "stdout")
> stdoutAppender = FileAppender(process.getInputStream, stdout, conf)
> val stderr = new File(baseDir, "stderr")
> val formattedCommand = builder.command.asScala.mkString("\"", "\" \"",
