Spark 动态上架下架worker

    xiaoxiao2021-12-14  19

    关闭 $SPARK_HOME/sbin/spark-daemon.sh --config conf/ stop org.apache.spark.deploy.worker.Worker 1 --webui-port 8081 spark://llc1:7077 开启 $SPARK_HOME/sbin/spark-daemon.sh --config conf/ start org.apache.spark.deploy.worker.Worker 1 --webui-port 8081 -c 24 -m 60G spark://llc1:7077

    使用命令

    $SPARK_HOME/sbin/spark-daemon.sh [--config <conf-dir>] (start|stop|status) <spark-command> <spark-instance-number> <args...>

    第一个参数 : –config $SPARK_HOME/conf 第二个参数 : start|stop|status 第三个参数 : org.apache.spark.deploy.worker.Worker(worker类的路径) 第四个参数 : 这个worker的号码,根据机器上已有的worker数来看 第五个参数 : 启动时的参数,下面是源码解析参数类 WorkerArguments.scala 中截取,都很清楚,传自己需要的参数即可

    private def parse(args: List[String]): Unit = args match { case ("--ip" | "-i") :: value :: tail => Utils.checkHost(value, "ip no longer supported, please use hostname " + value) host = value parse(tail) case ("--host" | "-h") :: value :: tail => Utils.checkHost(value, "Please use hostname " + value) host = value parse(tail) case ("--port" | "-p") :: IntParam(value) :: tail => port = value parse(tail) case ("--cores" | "-c") :: IntParam(value) :: tail => cores = value parse(tail) case ("--memory" | "-m") :: MemoryParam(value) :: tail => memory = value parse(tail) case ("--work-dir" | "-d") :: value :: tail => workDir = value parse(tail) case "--webui-port" :: IntParam(value) :: tail => webUiPort = value parse(tail) case ("--properties-file") :: value :: tail => propertiesFile = value parse(tail) case ("--help") :: tail => printUsageAndExit(0) case value :: tail => if (masters != null) { // Two positional arguments were given printUsageAndExit(1) } masters = Utils.parseStandaloneMasterUrls(value) parse(tail) case Nil => if (masters == null) { // No positional argument was given printUsageAndExit(1) } case _ => printUsageAndExit(1) }

    一个例子

    $SPARK_HOME/sbin/spark-daemon.sh --config conf/ start org.apache.spark.deploy.worker.Worker 1 --webui-port 8082 -c 4 -m 9G spark://llc1:7077
