Hi Qi Yun Liu,
This method is what you are looking for : stacks/HDP/2.0.6/services
HDP206StackAdvisor#getHostsWithComponent
Example:
datanodeHosts = self.getHostsWithComponent("HDFS", "DATANODE", services, hosts)
In: stacks/HDP/2.2/services/
HDP22StackAdvisor#recommendHDFSConfigurations
BR,
Sid

Hi Experts,
How to get datanode numbers in
stack_advisor.py#recommendHDFSConfigurations(self, configurations,
clusterData)? using its input parameters 'self', 'configurations' or
'clusterData'. At the same time, another method 'def
getComponentLayoutValidations(self, services, hosts)' has a input parameter
'services', so it could get nameNodeHosts using 'services', but I failed to get
parameter 'services' in method recommendHDFSConfigurations.
Any comments?
Thanks a lot!
