The UI warning was quite easy to resolve. I'm currently testing Solr
with HDFS but for some reason the core ended up on the local storage of
the node. After a delete and restart the problem was gone.

Right, I had to do that multiple times already when I restarted nodes
during collection creation. In such cases I was left with data in the
clusterstate.json, which at least on 6.2.1, blocked further collection
creations. Once manually deleted or set to {} collection creation worked
again.

Let us know how it goes. You'll probably want to remove the _contents_
of clusterstate.json and just leave it as a pair of brackets , i.e. {}
if for no other reason than it's confusing.
Times past the node needed to be there even if empty. Although I just
tried removing it completely on 6x and I w
Hi Erik,
I have actually also seen that behavior already. So will check what
happens when I set that property.
I still believe I'm getting the clusterstate.json set already before the
node comes up again. But I will try to verify that further tomorrow.
thanks,
Hendrik

Historically in 4.x, there was code that would reconstruct the
clusterstate.json code. So you would see "deleted" collections come
back. One scenario was:
- Have a Solr node offline that had a replica for a collection.
- Delete that collection
- Bring the node back
- It would register it
You are right, the code looks like it. But why did I then see collection
data in the clusterstate.json file? If version 1 is not used I would
assume that no data ends up in there. When explicitly setting the state
format 2 the system seemed to behave differently. And if the code always
uses version
Actually the state format defaults to 2 since many releases (all of
6.x at least). This default is enforced in CollectionsHandler much
before the code in ClusterStateMutator is executed.
