Google is crowing about how in nearly all the MAPR shops, their first step will be to the cloud PaaS solutions and don't see the risk with moving to CLDR as a viable option. GCP is targeting them with active marketing like never before.
Direct customer quote: "We don't see a need for a different Hadoop platform in our future after MAPR (gets decommissioned)"
What this means is that CLDR will get some companies to switch, but, it would be foolish to think lion's share of existing customers will switch to CLDR. Huge amounts of unused resources are going to flood the grey market here shortly.
