Last post we understood how important is the topology awaress when deploying Hadoop Cluster.
In order to vSphere Big Data Extension be able to leverage your topology awareness, you need to fill the system with your topology information.
If you did not provide any topology information the only method available will be HOST_AS_RACK
Let's see how can we provide topology information to BDE
- First, start creating a text file with your rack information
The format is rackname: host1, host2, host3
rack01, esxi01.local, esxi02.local
rack02, esxi03.local, esxi04.local
obs: rack name can be anything you want
If HVE is available for your Hadoop distribution, it will also shows on the list (not my case).
