Hi Naga, The host to host_group mappings are defined in the cluster setup call.
I'm having a problem however which I never encountered when I performed a manual installation. I'm running into this: resource_management.core.exceptions.Fail: Execution of 'ambari-sudo.sh su hdfs -l -s /bin/bash -c 'ulimit -c unlimited ; /usr/hdp/current/hadoop-client/sbin/hadoop-daemon.sh --config /usr/hdp/current/hadoop-client/conf start datanode'' returned 1. Error: JAVA_HOME is not set and could not be found. This seems to occur on all nodes when it attempts to start the services. Is this a known issue? Thanks!
