How does spark support connecting to two different databases in a single app

You can create 2 different dataframes with 2 different jdbc sources(one with mysql and another one with postgres) and make sure both the jdbc jars are present in spark's classpath.

Previously data transfer was from sqoop to hive and then any target db
