How to setup a cluster count:

[#1]

Hi,

Can you please help me understand how would we know how to setup a cluster depending on the size of the data and in HA mode and without HA mode. Please excuse if this is a simple question.

Hi @sujitha sanku that's a big question to answer in a short response, but probably the best resource to point you at is the high level sizing calculator which we have on-line here: http://hortonworks.com/blog/how-to-size-your-hadoop-cluster/

There's also a whitepaper linked from there too.

Finally, do check out the cluster planning guide documentation for HDP as well:

Hope that helps!

One more thing to add is that HA mode or non HA mode only adds one or two nodes when you're getting started, and isn't dependant on how much data you have. Very large clusters may well have more master nodes to further distribute the services of course.
