Re: [Announce] Solr-RA, Solr with RankingAlgorithm
Hi Nagendra,
I tried to use solr-nrt-ra-3.4, while the dataimporthandler does not work.
The error message is:
INFO: created /dataimport:
org.apache.solr.handler.dataimport.DataImportHandler
Dec 6, 2011 1:16:18 AM org.apache.solr.common.SolrException log
SEVERE: java.lang.IncompatibleClassChangeError: Implementing class
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631)
The nrt feature is critical to my app, what would be wrong with it?

Spark:
The code is compiled to be compliant with JDK 1.5 and above. So you will
need to use at least JDK 1.5 for this to work.
BTW, make sure you add the lib path to the dataimporthandler-3.4.0.jar
in you solrconfig.xml. If you want your data import to be searchable in
real time, please make sure you add the below to your solrconfig.xml as
well:
<realtime visible="200">true</realtime>
