When you copy a large file from the local file system to DBFS on S3, the following exception can occur:
Amazon.S3.AmazonS3Exception: Part number must be an integer between 1 and 10000, inclusive
This is an S3 limit on segment count. Part files can only be numbered from 1 to 10000, inclusive.
To prevent this exception from occurring, increase the size of each part file. Set the following property at the cluster level or notebook level.
Cluster Level: you must restart the cluster after setting this property.
If the error still occurs, increase the multipart size even more.
