Screenshots

If applicable, add screenshots to help explain your problem.

Which version of Dolphin Scheduler:
-[1.3.1-release]

Additional context
1.HeartBeatTask#run, send message to zk for report
2.zk property value format
"cpuUsage,memoryUsage,loadAverage,availablePhysicalMemorySize,maxCpuloadAvg,reservedMemory,startTime,updatetime.status,processid"
HeartBeatTask#run

StringBuilder builder = new StringBuilder(100); builder.append(OSUtils.cpuUsage()).append(COMMA); builder.append(OSUtils.memoryUsage()).append(COMMA); builder.append(OSUtils.loadAverage()).append(COMMA); builder.append(OSUtils.availablePhysicalMemorySize()).append(Constants.COMMA); builder.append(maxCpuloadAvg).append(Constants.COMMA); builder.append(reservedMemory).append(Constants.COMMA); builder.append(startTime).append(Constants.COMMA); // index 6 builder.append(DateUtils.dateToString(new Date())).append(Constants.COMMA); //index 7 builder.append(status).append(COMMA); //save process id builder.append(OSUtils.getProcessID());

3.WorkerGroupService#getWorkerGroups get zk path value and parse

String registeredIpValue = zookeeperCachedOperator.get(workerGroupPath + "/" + childrenNodes.get(0)); wg.setCreateTime(DateUtils.stringToDate(registeredIpValue.split(",")[3])); // split twice and error wg.setUpdateTime(DateUtils.stringToDate(registeredIpValue.split(",")[4]));// split twice and error
`

4. update

String[] splitedRegisteredIpValue = registeredIpValue.split(","); wg.setCreateTime(DateUtils.stringToDate(splitedRegisteredIpValue[splitedRegisteredIpValue.length-3])); wg.setUpdateTime(DateUtils.stringToDate(splitedRegisteredIpValue[splitedRegisteredIpValue.length-4]));
