> Container fails where there is a serialization problem in tuple recording
> -------------------------------------------------------------------------

> Key: APEXCORE-732
> URL: https://issues.apache.org/jira/browse/APEXCORE-732
> Project: Apache Apex Core
> Issue Type: Bug
> Reporter: Pramod Immaneni
> Assignee: Pramod Immaneni
> Priority: Minor
>
> Tuple recording is an optional feature used to record data for debugging
> purposes. If there are exceptions while saving the recorded data or
> transporting it to the client they are logged and processing continues,
> however, if there is an issue in the serialization it is not caught causing
> the container to fail. This serialization is json based and does not have any
> relation to the serialization of tuples between operators which could still
> be fine even though this serialization is having a problem.
