Steve Rowe created SOLR-9765:
--------------------------------

             Summary: In SolrCloud mode, schema modification should fail the 
operation and rollback to previous schema on all replicas if any replica fails 
to load the new schema
                 Key: SOLR-9765
                 URL: https://issues.apache.org/jira/browse/SOLR-9765
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Steve Rowe


When a schema modification request succeeds on the coordinating replica but 
fails on one or more other replicas, the request should fail and the schema 
should be rolled back to the pre-request schema on all replicas.

An example of where this should have happened but didn't: SOLR-9751.

Another scenario where this might occur: if nodes don't all have the same 
classpath, schema modifications might succeed on one node but not on another.
