Hi, starting with elasticsearch 0.9.6 i get spammed with the message: Caused by: java.lang.IllegalArgumentException: A SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene45' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath.The current classpath supports the following names: [Lucene40, Lucene3x, Lucene41, Lucene42, SimpleText, Appending] at org.apache.lucene.util.NamedSPILoader.lookup(NamedSPILoader.java:109) at org.apache.lucene.codecs.Codec.forName(Codec.java:95) at org.apache.lucene.index.SegmentInfos.read(SegmentInfos.java:332) at org.apache.lucene.index.SegmentInfos$1.doBody(SegmentInfos.java:380) at org.apache.lucene.index.SegmentInfos$FindSegmentsFile.run(SegmentInfos.java:812) at org.apache.lucene.index.SegmentInfos$FindSegmentsFile.run(SegmentInfos.java:663) at org.apache.lucene.index.SegmentInfos.read(SegmentInfos.java:376) at org.apache.lucene.index.IndexWriter.(IndexWriter.java:711) at org.elasticsearch.index.engine.robin.RobinEngine.createWriter(RobinEngine.java:1356) at org.elasticsearch.index.engine.robin.RobinEngine.start(RobinEngine.java:252) at org.elasticsearch.index.shard.service.InternalIndexShard.performRecoveryPrepareForTranslog(InternalIndexShard.java:573) at org.elasticsearch.indices.recovery.RecoveryTarget$PrepareForTranslogOperationsRequestHandler.messageReceived(RecoveryTarget.java:379) at org.elasticsearch.indices.recovery.RecoveryTarget$PrepareForTranslogOperationsRequestHandler.messageReceived(RecoveryTarget.java:353) at org.elasticsearch.transport.netty.MessageChannelHandler$RequestHandler.run(MessageChannelHandler.java:269) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Also the logstash console is filled with these so it is hard to debug logstash (1.2.2) right now. Same for elastic 0.9.7. Can i fix this or can i disable the message somehow? Best, Mike -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I believe I saw a similar message a while ago while running a mixed version cluster. I didn't have time to debug it truly but was able to fix the problem by forcing removing the nodes with the old version. I think the problem has to do with not being able to move shards from a node with a newer version of lucene to a node with an older version, though I'm not 100% sure. It was a bad day.
