Description

The vertica adapter doesn't use explicit transactions, so speculative tasks can result in duplicate loads. The JDBC driver supports it so the fix is pretty minor. Also the JDBC driver commits synchronously and the adapter needs to report progress even if it takes longer than the timeout.
