The error seems to be related to writing data to a MongoDB data source, as indicated by the com.mongodb.spark.sql.connector.exceptions.DataException.

It appears that the error is occurring during the execution of a Spark job that involves writing data to a MongoDB data source. The error message shows that the write operation was aborted for a specific partition and task, and manual data cleanup may be required.

Here are some steps you can take to troubleshoot and resolve this issue:

  1. Check MongoDB Connection and Configuration: Ensure that the MongoDB connection details and configurations are correct. Verify that the MongoDB server is running and accessible from the Spark cluster.

  2. Review Data Schema and Types: Ensure that the data being written to MongoDB matches the expected schema and data types. Any discrepancies in the schema or data types can cause write failures.

  3. Check for Data Skew: Data skew can cause certain partitions to have significantly more data than others, leading to task failures. Review the data distribution and consider repartitioning the data to balance the load.

  4. Increase Resources: If the task is failing due to resource constraints, consider increasing the resources allocated to the Spark job, such as executor memory and cores.
