Need to close JDBC connections

[sammefford]

Line 72 of BulkLoadFromJdbcWithJoins calls getConnection without closing the connection. This creates a resource leak. Can you call the close() method on that connection?

Also in BulkExportToJdbc.

Vivek, could you use try-with-resources or a try & do the close in a finally block?
