Markus Jelsma commented on SOLR-5261: ------------------------------------- Yonik, i think there's a similar issue. Yesterday, just before you opened this issue we saw something similar. A slighly older trunk SolrJ could not talk to a trunk cluster older than september the 18th. We got a similar exception: {code} java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Map at org.apache.solr.common.cloud.ClusterState.collectionFromObjects(ClusterState.java:263) at org.apache.solr.common.cloud.ClusterState.load(ClusterState.java:231) at org.apache.solr.common.cloud.ClusterState.load(ClusterState.java:207) at org.apache.solr.common.cloud.ZkStateReader.createClusterStateWatchersAndUpdate(ZkStateReader.java:299) at org.apache.solr.client.solrj.impl.CloudSolrServer.connect(CloudSolrServer.java:238) at org.apache.nutch.indexer.solr.SolrUtils.getCloudServer(SolrUtils.java:108) at org.apache.nutch.indexer.solr.SolrUtils.getSolrServers(SolrUtils.java:65) at org.apache.nutch.indexer.solr.SolrWriter.open(SolrWriter.java:66) {code} We still see this exception with both client and server updated to today's trunk. > can't update current trunk or 4x with 4.4 or earlier binary protocol > -------------------------------------------------------------------- > > Key: SOLR-5261 > URL: https://issues.apache.org/jira/browse/SOLR-5261 > Project: Solr > Issue Type: Bug > Reporter: Yonik Seeley > Assignee: Yonik Seeley > Priority: Blocker > Fix For: 4.5, 5.0 > > Attachments: SOLR-5261.patch > > > Seems back compat in the binary protocol was broke broke sometime after 4.4 -- This message is automatically generated by JIRA.
