Shawn Heisey commented on SOLR-6239: ------------------------------------ [~mohsen], one instance of HttpSolrClient is supposed to be usable by multiple threads in parallel. The httpcomponents documentation says that BasicHttpClientConnectionManager can only make one connection at a time, so I would be very surprised to find that Solr is using that connection manager by default. The only place I can find BasicHttpClientConnectionManager in current Lucene/Solr code is in the replicator code for Lucene, which is not used by Solr. > HttpSolrServer: connection still allocated > ------------------------------------------ > > Key: SOLR-6239 > URL: https://issues.apache.org/jira/browse/SOLR-6239 > Project: Solr > Issue Type: Bug > Components: clients - java > Reporter: Sergio Fernández > Priority: Minor > > In scenarios where concurrency is aggressive, this exception could easily > appear: > {quote} > org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Invalid > use of BasicClientConnManager: connection still allocated. > Make sure to release the connection before allocating another one. > at > org.apache.solr.client.solrj.impl.HttpSolrServer.executeMethod(HttpSolrServer.java:554) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > at > org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:210) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > at > org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:206) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > at > org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:124) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:116) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:102) > ~[solr-solrj-4.9.0.jar:4.9.0 1604085 - rmuir - 2014-06-20 06:34:04] > {quote} > I wonder if there is any solution for it? -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
