I am trying to insert into the Glue Catalog table pointing to s3 location and reading from Redshift.
I am getting the below error, I am able to write directly to s3 without any issues. This issue started while trying to insert that is defined as parquet.
Spark 2.4 - EMR. This issue within just couple mins after data unloading from redshift and process starts.
