com.amazonaws.SdkClientException: Unable to execute HTTP request: Timeout waiting for connection from pool"

I encountered this error when writing a large size Parquet file onto an S3 bucket, "com.amazonaws.SdkClientException: Unable to execute HTTP request: Timeout waiting for connection from pool" I included the following, but still the job stops. [ { "Properties": { "fs.s3.maxConnections": "500", } } ] When I reduce the size of the data, everything works fine. Any insights would be very much appreciated. Thanks
