Error Message
ExecutionException occured: com.teneo.esa.icp.collection.ev.EVCollectionException: [#422300] Unexpected error - [#422300] Unexpected error - Unable to read batch from CSV within timeout
Cause
In a Clearwell Distributed Architecture environment, when Clearwell collection task runs, it connects to the EV targeted source to gather items and adds these items to CSV files, one CSV file per archive. It then adds these items in batch (one thousand items by default) to another group of CSV files and delete original CSV files. In the event that the task failed due to a communication failure between one of the nodes and the cluster master server, re-running the collection task will try to read one or more of the original CSV files that is/are no longer available. As a result, the collection task will continue to fail.
Resolution
To resolve the issue, create a new collection task using the Copy as collection task option so new CSV files can be created.
Follow steps below to resolve the issue:
1. Logon to the Appliance.
2. Click on All Collections.
3. Select the collection in question.
4. For the collection task that failed, click on the Action icon under the Actions column.
5. Select Copy as collection task to create a new task. This will build new list of items to collect in new CSV files.
6. Click on the Play button to run a newly created task.
If the communication issue between the cluster master server and nodes has been resolved, the task should now run successfully.
