The data piece is easy, use Distcp. There may be some discrepancies with it, but it should work.

The rest are not so straightforward. I don't have any that come to mind that aren't just build. I know that Ambari and CM both have APIs so configs can be pulled and imported but they probably don't play nice with each other.

I would like to clarify your goal here so I can try to dig up some information for you. Am I correct to assume based on the questions that you are looking to replace Hortonworks with Cloudera or are you trying to spin up a Cloudera cluster for comparison purposes?

Re: Options for migrating data and scripts from Hortonworks To Cloudera

Please guide me  I'm trying to send simple file from hortonworks to cloudera using distcp command but getting error
"could only be replicated to 0 nodes instead of minReplication (=1). There are 1 datanode(s) running and 1 node(s) are excluded in this operation".
I am looking to hear from you.

Thanks.
