Yes, tested on namenode HA as well. There is a scenario where HAWQ is already installed on a non-namenode-HA cluster, and then namenode-HA is enabled: this has not been tested, since HAWQ does not support namenode switching from non-HA to HA yet. Will ensure that this feature is supported when HAWQ supports this scenario. - Matt ----------------------------------------------------------- This is an automatically generated e-mail.
