Re: Move Role to another host

New Contributor

Hi @Fawze,


Great, It's Work for me. So update my Default replication factor : 1. This is temporary because i need to upgrade my server memory.

Missing replicas looks normal and HDFS status is good Health

Re: Move Role to another host



You said that any role can be moved. How is that done for ones like "HDFS Balancer" or JobHistory servers? These roles can't be added/moved via CM that I can see.
