Minor Description
The Change from JdbcUtils.saveTable(DataFrame, String, String, Property) to JdbcUtils.saveTable(DataFrame, String, String, JDBCOptions), not only incompatible to previous versions (so the previous code in java won't compile, but also introduced silly code change: One has to specify url and table twice like this:
JDBCOptions jdbcOptions = new JDBCOptions(url, table, map);
JdbcUtils.saveTable(ds, url, table,jdbcOptions);
Why does one have to supply the same things ulr, table twice? (If you don't specify it in both places, the exception will be thrown).
