joining multiple base view error via custom wrapper parquet file in S3.

Hi Team, I am getting below error while creating the derived view from joining multiple base view. Accessing the AWS S3 bucket data source from custom wrapper parquet file in S3. [CUSTOM WRAPPER] [ERROR] Received exception with message 'Error accessing Parquet file: Task java.util.concurrent.FutureTask@4e04dcee rejected from java.util.concurrent.ThreadPoolExecutor@49584170[Running, pool size = 6, active threads = 6, queued tasks = 0, completed tasks = 88]'

Hi, Based on the error message “[CUSTOM WRAPPER][ERROR]”, it looks like the error is coming from the custom wrapper and not the join operation. Please confirm that the base views that you are using are working properly and you have correctly configured your custom wrapper. For more information, please refer to the [How to integrate Amazon S3 with Denodo Distributed File System Custom Wrapper](https://community.denodo.com/kb/view/document/How%20to%20integrate%20Amazon%20S3%20with%20Denodo%20Distributed%20File%20System%20Custom%20Wrapper?category=Data+Sources) document. If you are a Denodo Customer, I recommend you to open a Support Case to better assist you. Hope this helps!
