Subject [jira] [Commented] (SOLR-4473) Reloading a core will not close (leak) associated DIH JDBC connection
Date Tue, 19 Feb 2013 23:51:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13581772#comment-13581772
] 

Alexandre Rafalovitch commented on SOLR-4473:
---------------------------------------------

My top of config:
<dataConfig>
  <dataSource name="dbds" type="JdbcDataSource"
    driver="org.apache.derby.jdbc.EmbeddedDriver"
    url="jdbc:derby:${solr.solr.home}/test-dihnested/dihdb-content"
    user="app" password="app" />

I can provide a full core zip if it is too hard to replicate from the above description.

> I have DIH configured with Derby database. After I start Solr, I can run DIH import fine.
After I reload the core, DIH can no longer run with the following message (excerpts):
