I had some problems with DELETE action too. I reported this some time ago https://issues.apache.org/jira/browse/SOLR-5559
The overseer fail to delete a collection and the solr cluster becomes unstable, I reloaded my boxes and my cluster never went online. After some debug, I found some shard folder with the name of the collection that I was delete previously. I deleted it and the cluster went online again. You will need to remove all entries of deleted collection manually on clusterstate.json (if exists any). -- Yago Riveiro Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Thursday, February 27, 2014 at 10:42 AM, Oliver Schrenk wrote: > Hi, > > Upgraded a small cluster from 4.3.1 to 4.7 in Solr Cloud mode. > > I deleted the old data, replaced the solr.xml with the example solr.xml with > auto-discovery, but it seems there is still some old data somewhere, probably > in Zookeeper that keep my machine from starting. > > It loops over the same log message over and over > > 2014-02-27 11:00:49,011 INFO o.a.s.c.c.ZkStateReader [Thread-15] Updating > cloud state from ZooKeeper... 2014-02-27 11:00:49,012 INFO > o.a.s.c.Overseer$ClusterStateUpdater [Thread-15] Removing collection: > collection1 shard: 2 from clusterstate 2014-02-27 11:00:49,012 ERROR > o.a.s.c.Overseer$ClusterStateUpdater [Thread-15] Exception in Overseer main > queue loop org.apache.solr.common.SolrException: Could not find > collection:collection1 at > org.apache.solr.common.cloud.ClusterState.getCollection(ClusterState.java:175) > at > org.apache.solr.cloud.Overseer$ClusterStateUpdater.removeShard(Overseer.java:801) > at > org.apache.solr.cloud.Overseer$ClusterStateUpdater.processMessage(Overseer.java:230) > at org.apache.solr.cloud.Overseer$ClusterStateUpdater.run(Overseer.java:187) > at java.lang.Thread.run(Thread.java:722) > > How can I delete that false information? > > Regards > Oliver > > >
