             Summary: Core admin action "CREATE" fails to persist some settings 
in solr.xml
                 Key: SOLR-4862
                 URL: https://issues.apache.org/jira/browse/SOLR-4862
             Project: Solr
          Issue Type: Bug
          Components: multicore
    Affects Versions: 4.3
            Reporter: André Widhani
            Priority: Minor


When I create a core with Core admin handler using these request parameters:

action=CREATE
&name=core-tex69bbum21ctk1kq6lmkir-index3
&schema=/etc/opt/dcx/solr/conf/schema.xml
&instanceDir=/etc/opt/dcx/solr/
&config=/etc/opt/dcx/solr/conf/solrconfig.xml
&dataDir=/var/opt/dcx/solr/core-tex69bbum21ctk1kq6lmkir-index3

in Solr 4.1, solr.xml would have the following entry:

    <core schema="/etc/opt/dcx/solr/conf/schema.xml" loadOnStartup="true" 
instanceDir="/etc/opt/dcx/solr/" transient="false" 
name="core-tex69bbum21ctk1kq6lmkir-index3" 
config="/etc/opt/dcx/solr/conf/solrconfig.xml" 
dataDir="/var/opt/dcx/solr/core-tex69bbum21ctk1kq6lmkir-index3/" 
collection="core-tex69bbum21ctk1kq6lmkir-index3"/>

while in Solr 4.3 schema, config and dataDir will be missing:

    <core loadOnStartup="true" instanceDir="/etc/opt/dcx/solr/" 
transient="false" name="core-tex69bbum21ctk1kq6lmkir-index3" 
collection="core-tex69bbum21ctk1kq6lmkir-index3"/>

The new core would use the settings specified during CREATE, but after a Solr 
restart they are lost (fall back to some defaults), as they are not persisted 
in solr.xml. I should add that solr.xml has persistent="true" in the root 
element.
