I have a CDH4.1 cluster with 30 TB of HDFS space across 12 nodes. I now want to uninstall CDH and move the cluster to HDP. Nothing wrong with CDH, but want to try moving between distros without losing the data on datanodes.
Is it possible to re-map the same datanodes and pre-populated HDFS data disks on existing datanodes to HDP ? The goal is to uninstall CDH, install HDP on the same datanodes without migrating the existing HDFS data. Any leads appreciated.
