             Summary: Being able to configure the updates log implementation from solrconfig.xml
                 Key: SOLR-6819
                 URL: https://issues.apache.org/jira/browse/SOLR-6819
             Project: Solr
          Issue Type: Improvement
          Components: SolrCloud, update
    Affects Versions: Trunk
            Reporter: Renaud Delbru


CDCR requires its own implementation of the updates log. At the moment, there is no way to configure the class to use when instantiating the updates log. The UpdateHandler is deciding to instantiate the base class UpdateLog or its hdfs version HdfsUpdateLog based on the directory path prefix.
We can extend the UpdateHandler to allow for a class parameter to be defined for the updateLog section of the solrconfig.xml. For example, the relevant part of the solrconfig,xml will look like:
{code:xml}
  <updateHandler class="solr.DirectUpdateHandler2">
    <updateLog class="solr.CdcrUpdateLog">
      <str name="dir">${solr.ulog.dir:}</str>
    </updateLog>
  </updateHandler>
{code} 
where the updateLog entry has a parameter class that indicates that the CdcrUpdateLog implementation must be used.
