Create new CDH cluster with existing data nodes (recover data)

[ Edited ]

I had a CDH 5.4.4 Cluster with 1 cloudera manager, 2 name nodes and 7 data nodes.

The cloudera manager and 2 name nodes are dead and lost (no backup).

The 7 data nodes are intact.

Is there a procedure to recover/remount the HDFS and HBase from the existing data nodes by building a new cluster with new name nodes and joining the existing data nodes with their existing data?


Thanks all!
