Vamsee Yarlagadda commented on SOLR-7124:
-----------------------------------------
Looks like "zkcli .. -cmd clear <znode>" can delete the znodes recursively. So
a user can call this for /solr/configs/<ConfigName> to delete a config.
https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/java/org/apache/solr/cloud/ZkCLI.java#L236
I agree the users didn't have the direct option to delete the config (similar
to upconfig, downconfig). It would be good to have one.
bq. It should refuse to delete a config that is in use by any current
collection.
We should also keep in mind that a user can replace existing configs for a
collection and call collection RELOAD. So adding this check can prevent one
from easily replacing configs. Thoughts?

> As far as I know, there is no functionality included with Solr that can
> delete a SolrCloud config in zookeeper.
> A "delconfig" command should be added to ZkCli and the zkcli script that can
> accomplish this. It should refuse to delete a config that is in use by any
> current collection.
