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?
