You'll basically need to re-create the cluster in Cloudera Manager with the
same configuration as what you had before. CM won't delete any of your
data, so it should be possible to recover everything you had before (other
than whatever was stored on the host that died, of course). If you used the
default locations of all data dirs, this should be pretty straightforward.
Hopefully your oozie / hive / hue / etc databases weren't on the host that
died, as those will be more irritating to recreate.
Remember to take regular database backups of your databases, especially if
you're running on flaky machines.

We have 5 node hadoop (CDH 4.6.0) cluster created using Cloudera

Now I have created new VM for Cloudera Manager. After pointing VMs having
existing hadoop cluster to new Cloudera Manager, these VMs are showing as
managed hosts in CM.
However when I check for the HDFS service, it is not running on any node.
How to make Cloudera manager manage Hadoop Cluster and make sure that data
is HDFS is not lost ?
Any help is greatly appreciated.
