----------------------------------

Update:  

- Now there are patches in for BIGTOP-1200 and BIGTOP-952.   

- I've integrated the "oozie straggler" commands which arent in BIGTOP-1200 as pure shell calls.  So no need for any extra commands in this JIRA.

- Once those go in they can serve as a prototypical replacement for init-hdfs.sh,

Sp the main task in this JIRA will be:

- Update puppet provisioners
- Make sure that groovy and itest jar are available at setup time so that shell commands can run from the groovy provisioner. 
- Test it all by provisioning a hadoop system from scratch, without init-hdfs.sh
- delete init-hdfs.sh

> BIGTOP-1200 provides file schema in JSON format, for any HCFS related tool to read. 
> BIGTOP-952 meanwhile give us fast provisioning by running in a single JVM (without multiple haoop fs -... commands_).
> Thus, when those two are finished, we can replace init-hdfs.sh (with the exception of a few extra shell commands in bottom of that script which still will need to be called).  
> So this JIRA  will: 
> - create a new init-hcfs.groovy script which calls provision.groovy in BIGTOP-952, with init-hcfs.json as input. 
> - add in the remaining straggler commands from init-hdfs.sh which dont fit into the generic json format as shell commands.
> - delete init-hdfs.sh entirely
> - update puppet scripts to use init-hcfs.groovy, calling them with the "hdfs" argument.
