Hello, We were testing nutch configurations and apparently we got heavy handed with our approach to stopping things.
Now when nutch starts indexing solr, we are seeing these messages: org.apache.solr.common.SolrException: Lock obtain timed out: SingleInstanceLock: write.lock org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: SingleInstanceLock: write .lock at org.apache.lucene.store.Lock.obtain(Lock.java:85) at org.apache.lucene.index.IndexWriter.init(IndexWriter.java:1140) at org.apache.lucene.index.IndexWriter.<init>(IndexWrite r.java:938) at org.apache.solr.update.SolrIndexWriter.<init>(SolrIndexWriter.java:116) at org.apache.solr.update.UpdateHandler.createMainIndexWriter(UpdateHandler.java:122) at org.a pache.solr.update.DirectUpdateHandler2.openWriter(DirectUpdateHandler2.java:167) at org.apache.solr.update.DirectUpdateHandler2.addDoc(DirectUpdateHandler2.java:221) at org.apache.so lr.update.processor.RunUpdateProcessor.processAdd(RunUpdateProcessorFactory.java:59) at org.apache.solr.handler.XmlUpdateRequestHandler.processUpdate(XmlUpdateRequestHandler.java:196) I've looked through the configuration file. I can see where it defines the lock type and I can see the unlock configuration. But I don't see where it specifies the lock file. Where is it? What is its name? Also, to speed up nutch, we changed the configuration to start several map tasks at once. Is nutch trying to kick off several solr sessions at once and is that causing messages like the above? Should we just change the lock to simple? Thanks, Steve Cohen
