Hi Vishal, There is no specific reason why Flink does not have a Nomad HA implementation other than it has not been done yet. As long as Nomad supports leader election, service recovery and persisting small data it should be possible to implement HighAvailabilityServices against it. The best pointers to get started would be the implementation of the HighAvailabilityServices [1,2].
If you would like to contribute such a feature, then please open a JIRA ticket for it.
