Subject Re: ZooKeeperException: Could not find configName for collection
Date Wed, 06 May 2015 15:05:43 GMT
Have you looked arond at your directories on disk? I'm _not_ talking
about the admin UI here. The default is "core discovery" mode, which
recursively looks under solr_home and thinks there's a core wherever
it finds a "" file. If you find such a thing, rename it
or remove the directory.

Another alternative would be to push a configset named "new_core" up
to Zookeeper, that might allow you to see (and then delete) the
collection new_core belongs to.

It looks like you tried to use the admin UI to create a core and it's
all local or something like that.
