I am using solr 7.7.2 solr cloud
We version our collection and config set names with dates. I have two
collections sial-catalog-product-20200711 and sial-catalog-product-20200808. A
developer uploaded a configuration file to the 20200711 version that was not
checked into our source control, and I wanted to retrieve is from zookeeper as
we cannot find the version anywhere else. So I tried the zkcli.sh shell script.
It always throws an exception when trying to access
sial-catalog-product-20200711 but not when trying to access
sial-catalog-product-20200808

I can see both collections and configsets in the SolrAdmin console. I can
download the file from sial-catalog-product-20200808 with no problem. As far as
I can tell the two config sets are accessible in the cloud, both config sets
and collections are available the only difference is that we have an alias set
to point to the newer one which is current, but the zkcli script does not use
the alias.
I tried both the getfile and downconfig commands and the behavior is consistent
I can always get to the later one but the 20200711 version gives the
NoNodeException
What is going on here?
A general comment, we use Zookeeper chroot, but the zkcli command doesn't seem
to care if I pass the root on the zkhost argument or not. I also noticed that
the zkcli command is poorly documented.
