In version 2.2.1 and 1.7
Class org.apache.nutch.indexer.solr.SolrWriter
Line 66
inputDoc.addField(solrMapping.mapKey(e.getKey()), val2);
String sCopy = solrMapping.mapCopyKey(e.getKey());
if (sCopy != e.getKey()) {
inputDoc.addField(sCopy, val2);
}
There is a string comparison "sCopy != e.getKey()" with a != and not an equals.
It basically never works right. Not sure if someone was trying to be clever but
even if those strings are the same they happen to be different objects. Which
I'm assuming is due to how the strings are serialized in from the config files.
Suggest its updated to
String sCopy = solrMapping.mapCopyKey(e.getKey());
if (!sCopy.equals(solrMapping.mapKey(e.getKey()))) {
inputDoc.addField(sCopy, val2);
}
