For example, a MapReduce batch job might index multiple files in the same job where some of the files contain old and new versions of the very same document, using the same unique document key. Typically, implementations of this interface forbid collisions by throwing an exception, or ignore all but the most recent document version, or, in the general case, order colliding updates ascending from least recent to most recent (partial) update. The caller of this interface (i.e. the Hadoop Reducer) will then apply the updates to Solr in the order returned by the orderUpdates() method. Configuration: If an UpdateConflictResolver implementation also implements <code>Configurable</code> then the Hadoop Reducer will call <code>Configurable.setConf(org.apache.hadoop.conf.Configuration)</code> on instance construction and pass the standard Hadoop configuration information.</div> </li> </ul> </div> <div class="summary"> <ul class="blockList"> <li class="blockList">  <ul class="blockList"> <li class="blockList"><a name="method_summary">  </a> <h3>Method Summary</h3> <table class="overviewSummary" border="0" cellpadding="3" cellspacing="0" summary="Method Summary table, listing methods, and an explanation"> <caption><span>Methods</span><span class="tabEnd"> </span></caption> <tr> <th class="colFirst" scope="col">Modifier and Type</th> <th class="colLast" scope="col">Method and Description</th> </tr> <tr class="altColor"> <td class="colFirst"><code><a href="http://download.oracle.com/javase/7/docs/api/java/util/Iterator.html?is-external=true" title="class or interface in java.util">Iterator</a><<a href="../../../../../../solr-solrj/org/apache/solr/common/SolrInputDocument.html?is-external=true" title="class or interface in org.apache.solr.common">SolrInputDocument</a>></code></td> <td class="colLast"><code><strong><a href="../../../../../org/apache/solr/hadoop/dedup/UpdateConflictResolver.html#orderUpdates(org.apache.hadoop.io.Text,%20java.util.Iterator,%20org.apache.hadoop.mapreduce.Reducer.Context)">orderUpdates</a></strong>(org.apache.hadoop.io.Text uniqueKey, <a href="http://download.oracle.com/javase/7/docs/api/java/util/Iterator.html?is-external=true" title="class or interface in java.util">Iterator</a><<a href="../../../../../../solr-solrj/org/apache/solr/common/SolrInputDocument.html?is-external=true" title="class or interface in org.apache.solr.common">SolrInputDocument</a>> collidingUpdates, org.apache.hadoop.mapreduce.Reducer.Context context)</code> <div class="block">Given a list of all colliding document updates for the same unique document key, this method returns zero or more documents in an application specific order.</div> </td> </tr> </table> </li> </ul> </li> </ul> </div> <div class="details"> <ul class="blockList"> <li class="blockList">  <ul class="blockList"> <li class="blockList"><a name="method_detail">  </a> <h3>Method Detail</h3> <a name="orderUpdates(org.apache.hadoop.io.Text, java.util.Iterator, org.apache.hadoop.mapreduce.Reducer.Context)">  </a> <ul class="blockListLast"> <li class="blockList"> <h4>orderUpdates</h4> <pre><a href="http://download.oracle.com/javase/7/docs/api/java/util/Iterator.html?is-external=true" title="class or interface in java.util">Iterator</a><<a href="../../../../../../solr-solrj/org/apache/solr/common/SolrInputDocument.html?is-external=true" title="class or interface in org.apache.solr.common">SolrInputDocument</a>> orderUpdates(org.apache.hadoop.io.Text uniqueKey, <a href="http://download.oracle.com/javase/7/docs/api/java/util/Iterator.html?is-external=true" title="class or interface in java.util">Iterator</a><<a href="../../../../../../solr-solrj/org/apache/solr/common/SolrInputDocument.html?is-external=true" title="class or interface in org.apache.solr.common">SolrInputDocument</a>> collidingUpdates, org.apache.hadoop.mapreduce.Reducer.Context context)</pre> <div class="block">Given a list of all colliding document updates for the same unique document key, this method returns zero or more documents in an application specific order.
