bbrowning opened a new pull request #2808: Create the required CouchDB system databases
URL: https://github.com/apache/incubator-openwhisk/pull/2808
 
 
   As of CouchDB 2.0, system databases don't automatically get created on
   startup and you have to do this manually. The process differs a bit
   for single nodes vs clusters, but since everything else in the Ansible
   scripts seems to assume single node this just sets things up that way.
   
   See the CouchDB docs at
   http://docs.couchdb.org/en/2.0.0/install/#single-node-setup for more
   info.
   
   This prevents errors constantly being logged by CouchDB with messages
   like `Error in process <0.22878.7> on node 'couchdb@couchdb0' with
   exit value: {database_does_not_exist ...` and `chttpd_auth_cache
   changes listener died database_does_not_exist` which can end up
   chewing through a lot of log disk space.
