Houston Putman commented on SOLR-14706:
---------------------------------------
I'm not able to recreate this failure. I wonder if it requires multiple nodes
to trigger, since I'm currently testing with a single node.
> Upgrading 8.6.0 to 8.6.1 causes collection creation to fail

> Generalized steps:

> it's working
> # download
> https://dist.apache.org/repos/dist/dev/lucene/lucene-solr-8.6.1-RC1-reva32a3ac4e43f629df71e5ae30a3330be94b095f2/solr/solr-8.6.1.tgz
> # Stop the server on all nodes
> # replace the 8.6.0 with 8.6.1
> # Start the server
> # via the admin UI create a collection
> # Observe failure warning box (with no text), check logs, find above trace
> Or more exactly here are my actual commands with a checkout of the 8.6.0 tag
> in the working dir to which cloud.sh was configured:
> # /cloud.sh new -r upgrademe
> # Create collection named test860 via admin ui with _default
> # ./cloud.sh stop
> # cd upgrademe/
> # cp ../8_6_1_RC1/solr-8.6.1.tgz .
> # mv solr-8.6.0-SNAPSHOT old
> # tar xzvf solr-8.6.1.tgz
> # cd ..
> # ./cloud.sh start
> # Try to create collection test861 with _default config
> For those not familiar with it the first command there with cloud.sh builds
> the tarball in the working directory and then makes a directory named
> "upgrademe" copies it to "upgrademe" unpacks it, sets up a chroot based on
> the path in (already running separate) zookeeper, and by default starts 4
> local nodes on ports 8981 to 8984 all with separate data directorys hosted
> under the "upgrademe" directory.
