Subject [jira] [Updated] (SOLR-8734) fix deprecation warnings for absent (maxMergeDocs|mergeFactor)
Date Wed, 24 Feb 2016 23:39:18 GMT

     [ https://issues.apache.org/jira/browse/SOLR-8734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christine Poerschke updated SOLR-8734:
--------------------------------------
    Attachment: SOLR-8734.patch

Attaching proposed warnings fix patch against master.

The proposed patch includes a fix/change of erroring/failing if a <maxMergeDocs|mergeFactor>
is combined with a <mergePolicyFactory> element whereas the [existing code|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/update/SolrIndexConfig.java#L250]
would ignore the <mergePolicyFactory> element and use the default <mergePolicy>
instead. Though perhaps that is too controversional a change in general or for any future
5.5.1 release in particular?

Is this expected?

> bq. Could you advise if/that the solrconfig.xml has a <mergePolicy> element (for
which deprecated warnings would appear separately) or that the solrconfig.xml has no <mergePolicyFactory>
element?

warnings would be expected-and-harmless though admittedly are confusing, and fixable.
