Dear community. 

   First sorry for my questions. I'm new in hadoop.


We want use free CDH 6.3.x Express editions.


Hardware info

  • 4 physical node in EXSI CLUSTER

CPU: 20 cores per node

RAM: 128GB per node (used by esxi estimated 3.2 GB)

HDD: 5.23 TB per node (Local attached storage)


Reference to VMWare Document.


I think below architect  (But as i understand it's not suitable for hd practice) 

  • Gateway(s) and Management Service -1 Qty
  • Masters - 3 Qty
  • Worker -1 Qty


If one cluster will be, consist from seven nodes.

Then for each VM machines

CPU- 8 Core

RAM: - 60 GB

HDD: - 400 GB (for / file system)

HDD for HDFS: - 423 GB  (for /data1)



P.S Then HDFS cluster will have only 1.2 TB  ????



Hardware questions:  What is your architect suggestions  ? How i can separate our HD for cluster ?

We want use Oracle Linux. Can we you Oracle Linux 8.x edition
