Stretch CDH on-prem to AWS

New Contributor

I am trying to figure out if anyone has stretched out on-prem CDH cluster to AWS and gracefully decom master and data nodes one at a time. The scenario playing in my head is,

  • Using CM on-prem, build out master and data nodes inside AWS and connect them to on-prem CM.
  • Wait until HDFS replication catches up.
  • Gracefully decom data nodes on-prem one at a time
  • Switch to standy master node(AWS) and make it active
  • Migrate CM to AWS

The above are generic quick thoughts. Looking for answers.
