-------------------------------------
Summary: Exception when starting a node with index replication
Key: SOLR-15481
URL: https://issues.apache.org/jira/browse/SOLR-15481
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: replication (java)
Affects Versions: 8.8.2
Reporter: Pascal Chollet
We are upgrading from solr 7.4 to 8.8.2 and are using leader/follower
replication, SolrCloud or distributed search is not being used.
When starting a follower node, there seem to be a whitelist check in
{{IndexFetcher}} done for the configured shards, even though there is no
sharding configured. The check throws the following exception: {{Invalid URL
syntax in "shards" parameter: null}}
A possible workaround for us was to pass
{{-Dsolr.disable.shardsWhitelist=true}} to solr, which will disable the
whitelist check entirely. However, this is missing in the index replication
documentation.
This is the exception being thrown:
