Re-post:
solr-8.11.2 on windows; on a standalone node `bin\solr.cmd create -c
mycore` succeeds with or without '-d myconfig' parameter.
On a 2-node cluster w/ external zookeeper 3.8.3 it fails with
'''
... Caused by: Can't find resource 'lang/contractions_it.txt' in
classpath or 'configs/mycore'
'''
-- again, with or without '-d myconfig' parameter. (And yes, there is
lang/contractions_it.txt in "myconfig".)
However,
'''
\server\scripts\cloud-scripts\zkcli.bat -cmd upconfig -zkhost
localhost:2181 -d myconfig -n mycore
'''
succeeds, and the subsequent
'''
bin\solr.cmd create -c mycore -d myconfig
'''
succeeds too.
So it seems that zookeeper works and the failure is in solr.cmd --
either it doesn't work as documented in
https://solr.apache.org/guide/8_11/solr-control-script-reference.html#configuration-directories-and-solrcloud
at all, or only on winders.
