Are you asking about hardware recommendations? Eric Sammer on his "Hadoop Operations" book, did a great job about this: For middle size clusters (until 300 nodes): Processor: A dual quad-core 2.6 Ghz RAM: 24 GB DDR3 Dual 1 Gb Ethernet NICs a SAS drive controller at least two SATA II drives in a JBOD configuration
The replication factor depends heavily of the primary use of your cluster. On 11/26/2012 08:53 AM, David Charle wrote:
hi what's the recommended nodes for NN, hmaster and zk nodes for a larger cluster, lets say 50-100+ also, what would be the ideal replication factor for larger clusters when u have 3-4 racks ? -- David 10mo.
