Hi all
We have Ambari HDP cluster ( HDP version - 2.6.4 ) , with 420 workers linux machines ( when each worker include data node and node manager service )
Unfortunately Ambari DB is damaged , and we not have Ambari DB dump , so we cant recover Ambari DB , so actually we not have Ambari and Ambari GUI
But HDFS disks on workers machines include HDFS data , and name node is still working with all data as ( journal/hdfsha/current/ ) and ( namenode/current )
So HDFS works without Ambari
So regarding what I said until now - it is possible install new Ambari cluster from scratch , and then add existing working HDFS data to the cluster ?
Dose hortonworks / cloudera have procedure for this process ?
