I posted the same question over on Technet but got no response, so I'm hoping somebody here might know!
Has anybody had a definitive answer as to if R Services for SQL 2016 is supported on Always-On Clusters? I know it isn't supported on Failover Clusters but the wording is quite specific to failover clusters. Or installed in on an always on cluster and it works?
"Do not install R Services on a failover cluster. The security mechanism used for isolating R processes is not compatible with a Windows Server failover cluster environment."
