Evans Ye commented on BIGTOP-1634:
----------------------------------

Hey [~michaelweiser] I got your point now. So topology settings and journal based HA should be the next steps after we get this in, correct? For the journalnode storage logic, I think its better to configure a different directory, but we can address this when we're actually implementing the journalnode logic.
Thanks for fixing the tachyon deployment, let me deploy *all* components on my side and see what's going on for others you mentioned.
I've applied your patch and now I can successfully deploy a cluster of hadoop and yarn. It seems we're getting close to the commit! Now, trys to enable kerberos. Will let you know the result:)

> As discussed on the DEV list:
> Update the puppet code to use self-contained, parametrised classes and proper scoping. Replace all extlookup calls bei either explicit or automatic hiera parameter lookups. Implement HA/non-HA alternative via hiera lookup hierarchy. Replace append_each from bigtop_util by suffix from stdlib. Do file imports via puppet:/// scheme. Remove bigtop_util because remaining function get_settings is not needed any more.
> Additionally: Add additional configuration options for zookeeper and yarn as well as a new class for journalnode configuration.
> I've separated it into two patches of ease of review:
> 0001: actual hiera/class conversion
> 0002: functional enhancements including journalnode configuration on top of that. Mainly meant as an example for ease of further expansion and containment of changes to single modules.
> This JIRA is meant for the stuff contained in 0001, the actual hiera conversion. I can resubmit 0002 as a separate JIRA if desired. Also it should be possible to backport 0002 to the current puppet code base without much fuss.
