Hi,
I am not an expert, but I am running a 5 machine cluster.
I do the following.
Machine 1: DataNode and NodeManager
Machine 2: ResourceManager (Yarn-Master) and ProxyServer
Machine 3,4,5: NameNode and SecondaryNameNode
If you like you can also start the slave-processes also on the
master-machines, so you are also using the diskspace of these. For me it
is not neccessary yet and I am using the master-nodes dedicatedly.
To define you just put into the hostname or ip-address into
etc/hadoop/[masters|slaves]. 1 host per line
Best regards

Hi experts,
What is the best for multinode Hadoop configuration in a small cluster
with 4 machines only.
How can we define master, secondarynamenode and datanodes in the
/hadoop/conf/masters and slaves files?
Thanks
