Migrator Error in NFA after Harvester or Console Installation.
You may encounter this error with NFA Harvester after an uninstall and reinstall attempt.
The Harvester installation fails with a migrator error in the migrator.log showing specifically this:
2015/06/04 14:06:13 INFO DriverManagerDataSource::setDriverClassName() - Loaded JDBC driver: com.mysql.jdbc.Driver
2015/06/04 14:06:15 WARN SqlPropInspector::exists() - Exception: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. message: Communications link failure

at com.ca.im.migrator.business.SqlPropInspector.exists(Unknown Source)
This happens because the Mysql service doesn't get properly installed during the re-installation, because the installation detects that it may already be installed.
