Terracotta Quartz集群环境下StatefulJob在Failover时状态数据丢失

我在Terracotta集群环境下使用Quartz集群（两个Server实例A和B），采用StatefulJob，使用jobdataMap记录任务执行次数（count）。

A和B启动后，job在A结点执行，当A结点宕机后，B结点开始执行job，但是此时获取的jobdataMap中没有任何数据，也就重新开始计数。

相同的代码配置jdbcJobStore时，failover后计数正确。

代码如下：

quartz.properties：

org.quartz.scheduler.instanceName = ReportControlScheduler
org.quartz.scheduler.instanceId = AUTO
orgorg.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5
org.quartz.threadPool.threadPriority = 4
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz_job.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true 

#TerracottaJobStore
#org.quartz.jobStore.class = org.terracotta.quartz.TerracottaJobStore
org.quartz.jobStore.class = org.terracotta.quartz.EnterpriseTerracottaJobStore
org.quartz.jobStore.tcConfigUrl = 10.4.46.121:9510

quartz_job.xml:

<?xml version='1.0' encoding='utf-8'?>

job代码：

import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.PersistJobDataAfterExecution;

@DisallowConcurrentExecution
@PersistJobDataAfterExecution
public class QuartzJob implements Job {

	public void execute(JobExecutionContext context) throws JobExecutionException {
		
		int count = 0;
		System.out.println(context.isRecovering());
		try {
			JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();

			if(jobDataMap.containsKey("count")){
				count = jobDataMap.getInt("count");
			}

			//显示job信息，count自动加1 System.out.println(context.getJobDetail().getDescription()+"--"+context.getTrigger().getDescription()+"--"+context.getScheduler().getSchedulerInstanceId()+"--"+context.getFireTime()+"---"+context.getNextFireTime()+"---"+count++);
			jobDataMap.put("count", count);
			
                       //在下列等待中关闭任意结点，自动failover
			System.out.println("开始等待");
			 try {
				Thread.sleep(5000);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			 System.out.println("结束等待");
			
		} catch (SchedulerException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
