Hello,
I am trying to experiment with my solr indexes with the patch open on JIRA - Codec for index-level encryption <https://issues.apache.org/jira/browse/LUCENE-6966> (LUCENE-6966). https://issues.apache.org/jira/browse/LUCENE-6966. I am currently trying to test this Custom codec with Solr to encrypt sensitive documents. I have applied this patch to cloned Lucene-solr trunk (branch 6.3 on my local machine) and used “ant compile” and “ant jar” to get the jar files. By using this custom codec I can make use of the custom codec(Posting -format) classes by overridden posting format in field type definations. <fieldType name="string" class="solr.StrField" sortMissingLast="true" docValues="true" *postingsFormat= "EncryptedLucene50"* /> But when I try to load this codec directly via Solrconfig.xml CodecFactory as below. <codecFactory class="org.apache.lucene.codecs.encrypted.DummyEncryptedLucene60Codec"/> Solr is not able to load the core and initialize the codec. I am getting the following error in my logs. java.util.concurrent.ExecutionException: org.apache.solr.common.SolrException: Unable to create core [test] at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:192) at org.apache.solr.core.CoreContainer.lambda$load$1(CoreContainer.java:526) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor.lambda$execute$0(ExecutorUtil.java:229) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.solr.common.SolrException: Unable to create core [test] at org.apache.solr.core.CoreContainer.create(CoreContainer.java:855) at org.apache.solr.core.CoreContainer.lambda$load$0(CoreContainer.java:498) ... 5 more Caused by: org.apache.solr.common.SolrException: class com.wk.codecs.encrypted.DummyEncryptedLucene60Codec at org.apache.solr.core.SolrCore.<init>(SolrCore.java:903) at org.apache.solr.core.SolrCore.<init>(SolrCore.java:776) at org.apache.solr.core.CoreContainer.create(CoreContainer.java:842) ... 6 more Caused by: java.lang.ClassCastException: class com.wk.codecs.encrypted.DummyEncryptedLucene60Codec at java.lang.Class.asSubclass(Class.java:3404) at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:540) at org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:625) at org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:590) at org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:583) at org.apache.solr.core.SolrCore.initCodec(SolrCore.java:1112) at org.apache.solr.core.SolrCore.<init>(SolrCore.java:847) ... 8 more I am new to solr and unable to track what is causing this error. Is it classpath issue or something else ? I will appreciate any feedback on this. Thanks, Mohit
