Timothy Potter commented on SOLR-7642:
--------------------------------------
This only affects 5.x and beyond since the 4.x line bootstrapped the
collection1 automatically.
Alternatively, if we don't want to support this, we should document the reason
in the ref guide.
> Should launching Solr in cloud mode using a ZooKeeper chroot create the
> chroot znode if it doesn't exist?

> If you launch Solr for the first time in cloud mode using a ZooKeeper
> connection string that includes a chroot leads to the following
> initialization error:

> The work-around for this is to use the scripts/cloud-scripts/zkcli.sh script
> to create the chroot znode (bootstrap action does this).
> I'm wondering if we shouldn't just create the znode if it doesn't exist? Or
> is that some violation of using a chroot?
