FAQ
During the initial installation. I chose a Custom role installation and
picked thhe HDFS and Mapred services to be installed. During the
installation it did not give me the choice to assign roles to my hosts. I
have the JT and NN with better hardware but Cloudera manager assigned the
Datanode role to it, the 2NN and the NN is on a Datanode intended server
etc... I tried deleting the services and the cluster and re-configure one
service (HDFS then Mapred) at a time but now the datanodes won't start. How
do I reset everything and reassign the roles properly to the hosts that I
choose?


Thanks
