Hi,
Could you help me to find a guideline or recommendation for standing up 4-node HBase cluster? I have read HBase in Action book and the book recommended not to have fewer than 10 nodes in a production cluster. However, due to budget constraint, we would like to begin with small cluster and expand it later depends on traffic and volume. I am thinking of putting roles on each nodes like below: *[1 Master Node]* NameNode Secondary Node Zookeeper HBase Master Resource Manager JohHistory Server *[3 Data Nodes]* DataNode Region Server NodeManager We will not run any heavyweight m/r jobs in backend to keep consistent low-latency, but I am concerning availability as above configuration doesn't have multi masters. Do you think it is safe to have HA configuration later when we can add more nodes or should I do it from the beginning? 1. Name Node HA 2. Three Zookeepers 3. Backup HBase Master Thank you, Dongsu
