-------------------------------------
Summary: SPLITSHARD fails with custom lib in solrconfig.xml
Key: SOLR-6890
URL: https://issues.apache.org/jira/browse/SOLR-6890
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.10.2
Environment: linux, java 8
Reporter: Nicholas Stuart
We have a cluster setup, and added a entry into the solrconfig to point to a
directory that holds some customer plugins, everything works fine with the
initial setup and replication servers.
If we try to split shards through the collection api with the following:
http://10.0.6.228:8983/solr/admin/collections?action=SPLITSHARD&collection=products&shard=shard2
The API reports an error:
..
<lst name="failure">
<str>
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error
CREATEing SolrCore 'products_shard2_0_replica1': Unable to create core
[products_shard2_0_replica1] Caused by: com.test.MyParser
</str>
</lst>
<str name="Operation splitshard caused exception:">
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
ADDREPLICA failed to create replica
</str>
<lst name="exception">
<str name="msg">ADDREPLICA failed to create replica</str>
<int name="rspCode">500</int>
</lst>
..
Looking in the server logs the ultimate exception is:

The configs are stored in an external zookeeper instance if that matters at
all. Let me know if anything else is needed for debugging purposes.
