v2 registry search/catalog interface not yet supported in collector

[nehaj27]

docker run --rm -v ~/.docker:/root/.docker -v ~/.docfg:/root/.dockercfg -v /var/run/docker.sock:/var/run/docker.sock -v $HOME/.banyan:/banyandir -v /home/nehajain/collector/data/userscripts:/banyancollector/data/userscripts -e BANYAN_HOST_DIR=$HOME/.banyan banyanops/collector localhost:50000 --registryproto=v2 

Running this command in the collector directory gives me :

[07:26:44 2019/05/27 +0000] [INFO] (main.checkRepoList:357) Repolist: /banyandir/hostcollector/repolist not specified

What else should I specify in the command?
