Serialization 无法在批处理步骤Mule ESB中捕获失败记录

我已对批处理流程进行了以下配置。

对于批处理作业-->max failed records=“-1”-这表示实例将处理所有记录，而不管失败记录的数量如何

   1.   Batch_Step: AcceptPolicy=  “All”
             So this being first batch step will accept all the records and process them.

   2.   Batch_Step1: AcceptPolicy= “ONLY_FAILURES”
                So this must accept only the records that got failed in the first batch Step.


      **The first batchstep has some dataweave transformation.
    The second batchstep as of know i am just logging and no transformation  is present.**

在Dataweave中，当出现一些不正确的记录（错误的数据）时，会发生异常，因此必须在第二步中捕获该不正确的记录

但我面临的问题是，第一批执行良好，并显示失败记录的计数

但控件根本不进入第二批处理步骤，控制台中存在PFB异常。（只有当某些记录在第一个批处理步骤中失败时，才会发生这种情况）。对于积极的场景，批处理步骤可以正常工作。根据我的观察，以下内容可能对日志控制台有用：无法对缓冲区“批处理队列缓冲区”上的作业“failedrecordspocBatch”的4条记录进行排队，例如“3b742880-98e1-11e5-9927-f0ea20524153”。记录将被标记为失败。处理块id为“3d066141-98e1-11e5-9927-f0ea20524153”

然而，通过下面的链接，我知道很少有有效负载无法序列化这是链接：

所以，我明白我需要实现Kryo序列化程序，这是我第一次听到

那么，有人能帮助我如何在批处理步骤流中实现Kryo序列化程序的概念吗

如果需要任何澄清，请发表评论。
