--------------------------------------
Summary: Java serialization error while operating a mixed mode
Solr cluster
Key: SOLR-7055
URL: https://issues.apache.org/jira/browse/SOLR-7055
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.10.3
Reporter: Hrishikesh Gadre
We are in the process of upgrading Solr cloud from 4.4.0 to 4.10.3. We setup a
mixed mode cluster having 1 node of version 4.10.3 and multiple nodes of
version 4.4.0. The overseer node was on the older version.
When we submitted the request to create a collection, it failed with following
exception,
