Hi all! I have a broad question that is proving difficult to answer conclusively.
When you import from MSSQL, we (my co-workers and I) understand that the initial connector communicates on port 1433 by default. However, when the map task created by sqoop imports the data to the data nodes, are the data nodes connecting to MSSQL via port 1433, or are arbitrary ports opened between the data nodes and the SQL Server? We need to know because we are interested in hosting data for a variety of clients, and need to be able to place firewall rules for our data center to manage access to our cluster while still connecting to various environments.
