This 'solrctl' command is NOT part of Solr.  Google tells me it's part of
software from Cloudera.

You need to talk to Cloudera for support on that software.

You're using the term "collection".  And later you mention ZooKeeper. So
you're almost certainly running in SolrCloud mode.  If your Solr is running
in SolrCloud mode, do not try to use the CoreAdmin API (/solr/admin/cores). 
Use the Collections API instead.  But before that, you need to get the
configuration into ZooKeeper.  For standard Solr without Cloudera's tools,
you would typically use the "zkcli" script (either zkcli.sh or zkcli.bat). 
See page 376 of the reference guide for that specific version of Solr for
help with the "upconfig" command for that script:

The solrctl command is not something we can help you with on this mailing
list.  Cloudera customizes Solr to the point where only they are able to
really provide support for their version.  Your best bet will be to talk to
Cloudera.

When Solr is running with ZooKeeper, it's in SolrCloud mode.  In SolrCloud
mode, you cannot create cores in the same way that you can in standalone
mode -- you MUST create collections, and all configuration will be in
zookeeper, not on the disk.
