Yonik Seeley resolved SOLR-1711. -------------------------------- Resolution: Fixed Fix Version/s: (was: 1.4.1) (was: 1.5) Committed the latest patch - hopefully that finally fixes this issue! > Race condition in > org/apache/solr/client/solrj/impl/StreamingUpdateSolrServer.java > ---------------------------------------------------------------------------------- > > Key: SOLR-1711 > URL: https://issues.apache.org/jira/browse/SOLR-1711 > Project: Solr > Issue Type: Bug > Components: clients - java > Affects Versions: 1.4, 1.5 > Reporter: Attila Babo > Assignee: Yonik Seeley > Priority: Critical > Fix For: 3.1, 4.0 > > Attachments: SOLR-1711.patch, StreamingUpdateSolrServer.patch > > Original Estimate: 1h > Remaining Estimate: 1h > > While inserting a large pile of documents using StreamingUpdateSolrServer > there is a race condition as all Runner instances stop processing while the > blocking queue is full. With a high performance client this could happen > quite often, there is no way to recover from it at the client side. > In StreamingUpdateSolrServer there is a BlockingQueue called queue to store > UpdateRequests, there are up to threadCount number of workers threads from > StreamingUpdateSolrServer.Runner to read that queue and push requests to a > Solr instance. If at one point the BlockingQueue is empty all workers stop > processing it and pushing the collected content to Solr which could be a time > consuming process, sometimes all worker threads are waiting for Solr. If at > this time the client fills the BlockingQueue to full all worker threads will > quit without processing any further and the main thread will block forever. > There is a simple, well tested patch attached to handle this situation. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
