RECOMMENDED PROCESSORS - a dual-socket server with Ivy Bridge processors clocked at between 2 and 2.5GHz.
RECOMMENDED MEMORY - 48GB of RAM is sufficient
RECOMMENDED STORAGE - use four >900GB LFF SAS drives because much higher capacities are available, as compared to smaller form-factor SAS drives.
If Edge Nodes are pass throughs then why do we need such high Storages ? Is there a better configuaration for Edge Nodes.
@Guru Kamath Considering Edge node's will just execute your jobs as a gateway, the main process will run on your slaves. In my opinion, you don´t need too much storage on Edge nodes, unless you need to use this space to store scripts, process, logs, and other files that you need to use as a part of your process. I suggest you use a separated filesystem to store your files.
And if possible use Edge node exclusively for gateway services, installing Ambari on another machine.
