Subject How to get datanode numbers in
Date Fri, 10 Apr 2015 07:09:18 GMT
Hi Experts,

How to get datanode numbers in, 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!
