I have installed hortonworks hdp platform on 5 node cluster.
@dhieru singh, if this is Ambari installed cluster, you can run service checks as below to validate cluster state.

Thanks @yvora, I just checked it and looks good for my use, however is there any help if it is not a Ambari installed cluster?
@dhieru singh, In this case, you will need to validate each service manually. Typically, smoke tests perform below checks.
* Check whether service is up or not
* If it has UI , check if UI page is accessible or not
* Run a simple sanity use case ( like submit sleep job in case of Hadoop )
Example: Follow below doc to validate health of Hadoop services manually.
