Hello, I´ve found what It seems to be a bug JIRA-SOLR4080<https://issues.apache.org/jira/browse/SOLR-4080?focusedCommentId=13498055&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13498055> with CloudSolrServer during atomic updates via SolrJ. Thanks to Sami I detected that the problem could be solved setting BinaryResponseParser as Parser and BinaryRequestWriter as Request writer. That workis with HttpSolrServer, but CloudSolrServer or LBHttpSolrServer hasn´t got any method to set them.
Is there a way to set both parsers to a CloudSolrServer instance? Do you know if maybe it could be configured insed solrconfig.xml? Thanks a lot. -- - Luis Cappa
