首先在Options类里加入jobId属性，然后在JobGraphUtil类的buildJobGraph方法修改调用 createJobGraph的方式

JobGraph jobGraph = null; if (StringUtils.isNullOrWhitespaceOnly(launcherOptions.getJobId())){ // use the jobId generated by flink when jobId is empty jobGraph = PackagedProgramUtils.createJobGraph( program, launcherOptions.loadFlinkConfiguration(), flinkConf.getInteger(DEFAULT_PARALLELISM), false); }else{ // use the customize jobId generated by flink when jobId is not empty jobGraph = PackagedProgramUtils.createJobGraph( program, launcherOptions.loadFlinkConfiguration(), flinkConf.getInteger(DEFAULT_PARALLELISM), new JobID(StringUtils.hexStringToByte(launcherOptions.getJobId())), false); }
