Yonik Seeley commented on SOLR-4028:
------------------------------------
bq. I think I see the issue here, the problem would be if someone mistype the
initial path, instead of throwing exceptions and stopping, we would be creating
a new path and probably hiding an error.
That can go the other direction too? A config could be created under /solr and
then someone could try to join it by forgetting to specify that root in zkHost.
bq. Only create the initial path when bootstrap_conf is true (or
bootstrap_confdir).
As long as we need some sort of explicit bootstrap, that seems reasonable.
bq. Add a new parameter to force creation, something like –DzkHost.create=true.
Anything that creates a skeleton layout of a new cluster should work the same
(auto-create the rot if it doesn't exist). "ZkCLI -cmd bootstrap" for example.
Not sure if there are others.

> I think this would make it easier to test and develop with SolrCloud, in
> order to start with a fresh ZK directory now the approach is to delete ZK
> data, with this improvement one could just add a chroot to the zkHost like:
> java -DzkHost=localhost:2181/testXYZ -jar start.jar
> Right now this is possible but you have to manually create the initial path.
